HARDWARE TROUBLESHOOTING IN PCB DEVELOPMENT AND DEBUG

11 Steps to Successful Hardware Troubleshooting in PCB Development and Debug

Among all the elements to be considered in the design of any embedded system, printed circuit board (PCB) development and debugging is the most challenging of all tasks involved. PCB is the point where all of the previous design decisions made are put together and where other unforeseen problems that are related to the performance, signal integrity, noise mismatching and power manifest themselves and they must be resolved at this point.

Resolving all these problems is becoming more challenging since integrated circuit (IC) design geometries are becoming more compact and extremely sensitive to the issues of crosstalk, jitter and electromagnetic interference. Other such issues emerge in the PCB itself and its packaging. Efforts aimed at increasing the functional density of the design through development of new smaller dimension pin-out techniques and multichip packaging present other signal integrity issues. Therefore, debugging this board often requires one to employ the skills of a detective so as to differentiatethe guilty and the innocent.

Dunstan Power points out that it’s always important to always remember that the work of board design is performed by a person who is fallible and may also be usingincorrect or incomplete data.He continues to say that some bugs are unavoidableexcept for the simple designs and hence the method of troubleshooting the bugs is all-important. Bugs range from the device going BANG on powering for the first time to other intermittent glitches. The ease of bug fixingusually ranges from a simple five-minute task to a month’swork.

Dunstan Power pointed out the following 11 steps to successful hardware troubleshooting in PCB development and debug;

Picture success

This is an important part of the debugging process and entails having the right mental attitude.This is because persistent problems may decrease your morale. It feels bad particularly when you are working for several successive days with the investigation process stuck at the same point.

Keep notes

It is crucial to first determine if other people have previously dealt with similar problems successfully. This helps one to resist the temptation to straightly dive into fixing the bug immediately.Often gather reports from other sources related to the bug to be solved.

Reproducing the problem

It is the most time-consuming and hardest part of the process. At this point, one needs to come up with the conditions that can create the bug at your command, based on the collected information. Therefore, diagnosis can begin at this point. Keep working until all the information from the person who gave the report about the problem is available and also sufficient to narrow down on list of possible causes.

Focus should be on reproducing the bug. Care has to be taken since some similar but totally different issues may appear to be as a result of the same bug, if one is masking the other. If any other bugs are discovered in the process of looking for the initial bug, a note of them should be made. They should be re-visited later on.

Gathering the evidence

Observations have to be document. At this point, a table of things that aggravate or alleviate the bug has to be created.

Trying the easy stuff first.

To reproduce the problem, first look for the easiest explanations. For example, is the wiring of connectors back-to-front? Are the pin-outs of the chip similar to the data sheet? Bugs are usually as a result of mistakes that are dumb in hindsight.

Break the problem down

In complex systems, many bugs may manifest similar symptoms on the surface.These bugs do require different remedies. Elimination of part of the system that is not relevant to the bug should be done to clarify the issue. For example, one could power down all the devices, which are unrelated, on the PCB, or eject cables from other boards. This is done while re-testing. If the bug stops after removal of an unrelated module, document it. Reproduction of the bug again, with and without the module should be done.

Talk it over with a colleague

Talking over intractable bugs with someone else may often help, even if the person is not from the same engineering discipline. Explaining your observations to someone might help you to view the bug from another different angle and realize an important fact. You may realize inconsistencies that require ironing out. You may also receive suggestions of different things to try.

Application of the fix

You gain understanding of the bug and will have developed a rational solution. Run the code.The problem will appear to be solved. Despite this, the task is not yet over.

Try to break it again

Try breaking the system once again. To make sure you had success, you have to subject the system to appropriate stress tests that are an order of magnitude that surpasses stress of the initial implementation.

For example, if a real-time system crashed after every ten minutes and could not last for more than an hour, but it now runs for over ten hours, the bug is almost fixed.

The system may behave better but may still crash. At this juncture, you may have come across another bug that was previously masked by the other bug. Therefore, one needs to go back again to step one and create a fresh new investigation on this “cured/corrected” system.

Remember ‘disappearing’ bugs are still there if you haven’t fixed them

In some cases, some bugs may appear to vanish by themselves. This can prove to be frustrating.One needs to note that they haven’t fixed this bug. These are the kind of bugs that usually reappear when a customer or the boss is present. The best thing to do is to document it and then continue looking into the other issues since it might return by itself. Although, you still have to go back and fix the bug at some point. Therefore, a lot of effort should to be applied in trying to reproduce the bug.

Celebrate

At this point, you have successfully fixed the bug.

Printed Circuit Boards for Surface Mount Technology

SMT Components Used in PCBs – A Detailed Overview

Surface Mount Technology (SMT) is a technique used for producing electronic circuits where components are mounted directly on the surfaces of the Printed Circuit Boards (PCBs). The resultant electronic device is called the Surface Mount Device (SMD). Previously, the through-hole technology where components are fitted with wire leads into the circuit board’s holes was used for the construction of PCBs and other electronic devices but was later replaced by the SMT. Surface Mount Technology has the merit of applying to all types and sizes of components with leads or no leads. Moreover, the SMT technique is cheaper than the thru-hole technology (THT). PCB Surface Mount Technology has grown over the past few years with such boards finding numerous applications in the industrial, medical, commercial, transportation, environmental, and consumer products fields.

We at RUSHPCB produce every type of SMT Printed Circuit Board no matter what the application could be. Our services are flexible and our team of experts is committed to ensuring that customer needs are satisfied. We have a reputation to prove it. Please visit us at https://www.rushpcb.co.uk/ and learn more about our range of products and services. You can also place a quote today and our team of experts will begin working on it immediately.

Why use PCBs for Surface Mount Technology?

Mass production of Printed Circuit Boards has to be done in an extremely mechanized manner to reduce manufacturing costs. Traditional leaded PCBs and other electronic components cannot be applied in this approach thus the need for SMTs since component leads can be pre-formed. Comparatively, after the leads were automatically inserted into boards, problems would be encountered since wires could not fit properly thus slowing the production rates.

Different from that, many designers were of the idea that wires which were traditionally used for connections were not relevant to the construction and fabrication of Printed Circuit Boards. It is, because of this reason that components were soldered onto pads on the PCB instead of having leads placed through holes hence the Surface Mount Technology. By the same token, this eliminated the need for creating lead holes in the boards which increased the cost of production of rare PCBs.

Different from that, to accommodate SMT, a new set of components was needed. To do this, the electronic PCB designers came up with new outlines that could oversee the application of the same components on the SMTs. Join us as we discuss some of the major Surface Mount Technology components used for Printed Circuit Boards. We produce SMT PCBs with the quality and the characteristics of the resultant board depending on your specifications. If you need a perfect SMT Printed Circuit Board, please do not hesitate to pay us a visit at https://www.rushpcb.co.uk/ and enjoy being served by professionals in the PCB world.

Major SMT components

Surface Mount Technology components vary depending on the applications of the Printed Circuit Board. These categories shall be discussed in detail below.

Passive Surface Mount Devices

There is a variety of various packages used for the passive SMDs. However, most of the passive SMDs employed in the PCBs for SMT are either capacitors or resistors with the quantity and rating of the components used depending on the application of the PCB. Equally significant, other SMD devices used for the Surface Mount Technology are crystals, coils any other equipment specified by the customer. Common designations of capacitors and resistors are 1812, 1206, 0805, 0603, 0403, and 0201 (dimensions are hundreds of an inch). The connection of passive SMDs to the PCBs is made using metalized areas at either end of the PCB.

Transistors and diodes

These components are mainly contained in small plastic packages with the connections being made via leads emanating from the package and a bend to touch the boards. The use of 3 leads is most common since the device positioning and mounting can be easily determined.

Integrated circuits

The variety of packages used for ICs (Integrated Circuits) varies depending on the interconnectivity levels needed. However, many chips such as the simple logic chips require 16 or 14 pins whereas other types of chips like the VLSI processors or associated require over 200 pins. For small chips, packages like SOIC (Small Outline Integrated Circuit) are used. Such packages are the SMT version of the Dual In Line (DIL) packages commonly used for the 74 series logic chips. As if that is not enough, smaller versions like the Thin Small Outline Package (TSOP) and Shrink Small Outline Package (SSOP)are also used in the market. However, VLSI chips demand an entirely different approach and mainly use the quad flat pack. This is a rectangular or square footprint with pins emanating from all 4 sides. The pins are bent out of the package (gull—wing information) to meet the board.

In the same token, an entirely different package available for the Integrated Circuits is the Ball Grid Array (BGA) where the connections are not made on the package’s side but instead, they are placed underneath. The connection pads have solder balls that melt during the soldering process thus making a good connection with the boards.

The Recommended Procedure To a Prototype for Hardware Startups

Hardware Startup Prototyping: A Guide by RUSHPCB Ltd

Creating a working prototype is the first step one has to go through if they have a new hardware device that they would like to sell or develop. So which is the first step to developing a prototype for a hardware setup? Well, we at RUSHPCB know that the hardware development procedure is tedious and the expected results might not be achieved at all. We, therefore, came up with a procedure where we split the whole process into two major sections’ the plastic and the electronics case.

We are professionals in the PCB world with the quality of PCB products and services that we offer to our customers improving day in day out. Pay us a visit at https://www.rushpcb.co.uk/ and place your quote today or interact with our sales representatives. Please join us as we discuss the two sections separately.

The Electronics Case

In this section, creating prototypes can be separated into 4 major steps. Since this section is very technical, we recommend that you hire a design engineer to design the electronics. We at RUSHPCB have qualified PCB design engineers so if you are interested in getting a PCB prototype visit us at https://www.rushpcb.co.uk/ and enjoy interacting with the experts.

Creation of an electronic blueprint or schematic

Creating an electronic blueprint (schematic) is the first step in electronic development. Schematics provide the significant details necessary in building the electronics and specifies how the components shall be connected together. In PCBs, this helps prevent cases of wrong component connections that might lead to damage of the components due to short-circuit. On the other hand, the BOM (Bill Of Materials) is also created to provide details of every electronic component used in the design.

Creating an intermediate prototype

This step is optional and it depends on your budget and the project that you are undertaking. The most common techniques used for this step are using breadboarding which uses methods to crudely connect the electronic components or using an existing development module like Raspberry Pi or Arduino. However, in modern PCBs, the immediate prototype can be created in any PCB design software like CAD. This is better since the software is readily available in the market.

Creating the PCB layout

The quality of a PCB prototype depends on the method used to create it. The creation of a prototype demands the creation of a Printed Circuit Board which is a designed board holding and connecting all the electronic components on the board. The components used depends on the characteristics of the board and its application. Moreover, the electronic engineer uses a special software to convert the blueprint to a real physical Printed Circuit Board layout. This is a complex procedure since the PCB layout has an appreciable effect on the efficiency of the final product. It is, for this reason that we (RUSHPCB) recommend that you use qualified electronic engineers for creating a PCB layout and prototype. We have such skills and expertise with our electronic engineers (PCB design engineers).

Electronics Fabrication

After the design of the PCB layout, the layout design files are passed to the production stage which is carried out by an electronics prototyping company. This is the first stage in the fabrication of an empty PCB. After the PCB is fabricated, it is assembled by soldering all the components into their designated positions. However, a high percentage of modern microchips have close pin spacing thus manual soldering becomes inefficient and automatic soldering is used instead.

The Plastic Case

This section is used where an electronic product is enclosed in aplastic case of a kind. However, creating a prototype of such a custom shaped case requires the application of 3D printing. This can be simplified into 2 stages as shall be discussed below. In the event that you have any query or you would like to place a quote. We offer reasonable prices to all customers and customer satisfaction is our priority.

Creating the 3D model

This is the initial step to create a computer model for the plastic parts of your product in 3D. Just like the PCB layout stage, this procedure is technical and it requires the expertise of a computer modelling (3D) expert. However, you can also do the modelling but you will have to obtain the expensive 3D modelling software first which is more expensive compared to the cost of hiring an expert.

3D printing

After completing the 3D model, the 3D design files are sent to a printer who does prototyping. This is a unique service since there are many prototype shops which offer 3D printing. However, if you need the printing of a Printed Circuit Board Prototyping, we recommend that you use experts who will not mess up in the printing stage. We offer this service and our team of experienced PCB prototype engineers is always ready to help our customers. On the other hand, a different option is to purchase your 3D printer although you will need the relevant skills to obtain a perfect output.

From the discussion above, you should note that a different technology is applied for the production of pieces of custom plastics in large scale. This technology is known as high-pressure injection modelling. Additionally, to transition a custom plastic design from the initial prototype to a full product is a costly and complex process. However, after obtaining a functional prototype, you can get begin getting customers, a manufacturing partner, initial feedback and investors.

The procedure to hardware startup is a long one and it all begins with the prototype. As discussed above, skills are needed in almost each stage; thus we recommend the use of experts to come up with a prototype for a hardware startup. We at RUSHPCB Ltd have experts in each stage discussed above, therefore, we come up with the prototype and proceed with the assembly stage until the final product is obtained as per your specifications.

Every year, smartphones and portable electronic devices hit the market promising the customers of a better future on the features and functionality and features of the components. Moreover, the robot technology has advanced significantly over years and a better future is foreseen in the same especially with the use of Printed Circuit Boards. In both smartphones and robot technologies, PCBs and the hardware inside make the operation of the component or device easier. The robotics and the smartphone industry are in a constant state of flux with the range of products changing depending on the environment and the operating specifications. Comparatively, the assembly calls for self-configuring and extremely flexible automatic devices which can be achieved by the use of a PCB. It is, therefore, clear that PCBs play crucial roles in the smartphone and robot technologies and they have a promising future in the same.

As an example, the Samsung Galaxy Note 4 was introduced to the market to deliver better NFC performance at higher radio frequencies. This is possible through the use of a chip that is small in size and operates with a double range in the card emulation and reader modes. Moreover, updating a smartphone or any other electronic component demands the delivery of more secure and safer features which can be added to the existing component. This calls for the improvement in the functionality of PCB with each new device continuously using PCB in their operation. Equally significant, apart from helping manufacturers incorporate entirely new features of smartphones, PCBs have played a role in helping reduce the size of the smartphone with much smaller phones expected to hit the market soon. Moreover, the smartphone industry promises that PCBs will in the future be bonded with a plastic bond so as to help achieve the desired thinness, weight, flexibility and reducing the number of connections. If you need a perfect PCB with high efficiency to help you achieve some of these features, please visit us at https://www.rushpcb.co.uk/ and place your quote today.

We are leaders in Printed Circuit Board manufacturing, assembly, design and fabrication and that is why we came up with this topic to discuss with you the future of PCBs on smartphones and the robot technology. Kindly visit us at https://www.rushpcb.co.uk/ and learn the variety of PCB products and services we offer. You can also place your quote with an assurance of a perfect and punctual delivery.

The application of PCBs in the robot technology began long ago with the invention of the first electronic autonomous robots with complex behavior by William Grey Walter. The hardware of a robot is constructed from a PCB as shown above. The PCB also serves as the chassis, motor and wheel, battery pack, infrared sensor and as a smartphone. Currently, with the advancement of technology, the robot platform uses a smartphone and a microcontroller. The smartphone’s sensors navigate the robot thus facilitating its flexibility and adaptability. Future technology promises the use of PCB on robots to provide for adapters connected to a robot to provide 3D printing. It is crucial to recall that previous robots were equipped with a FPGA, Gumstix Overo board and a microcontroller. However, with the use of Printed Circuit Boards, it is possible to integrate different categories of sensors, a display (user input buttons) and a camera. To ensure consistency in any data signal send, modern robots have PCBs which act as communication protocols with the first byte sent being a protocol byte and it indicate that driving commands are being transmitted. Sequentially, the robot can respond to various questions, gestures and responses by the use of several chips and sensors mounted on the PCBs which are used in its assembly. Better robots with the ability to perform human duties perfectly are expected to hit the market due to the consistent applicability of the rapidly and ever growing PCB technology in the industry.

On the other hand, in smartphones, PCBs are used to provide a high-quality integrated camera which enables it to take pictures in any environment. Moreover, to facilitate communication with other devices, modern smartphones are equipped with several interfacing components like NFC, USB, Blue-tooth and WiFi. Comparatively, the integrated touch display and the OS (Operating System) provide a user interface easing the use and efficiency of the device. All these tools combine to form a perfect and powerful smartphone which can be adjusted to be used in various robots which do not require sophisticated machinery to operate and manufacture. Such robots are the basic soccer application robot which is simple and easy to integrate.

The dilemmas for any product designer is the incorporation of the latest components in any design products and at the same time reduce the heat production and energy consumption as well. Luckily, with the invention of the rigid-flex Printed Circuit Boards, it is now possible for one to tweak the PCB design to come up with a perfect and permanent solution for the creation of a robot or smartphone with the desired characteristics. Moreover, the via hole construction in a PCB, the placement of components and the PCB laminate choice one one’s boards using the modern technology enables one to produce a Printed Circuit Board with a very high efficiency and meets the given specifications. As if that is not enough, advancement in technology will enable designers to easily use better PCB design software to perfect on the circuit board layouts and submit the design files with ease using Gerber Files or better ones so that manufacturability checks are easily done. In the same token, it will be possible to corrections on any DFM errors on a PCB with ease thus facilitating the production of highly efficient PCBs which can be used in the robot or smartphone technology.It is, therefore, safe to conclude that PCB manufacturers and design hold and determine the future of the design and capability of smartphones and the robot technology.

Is The Manufacturing of Electronics Crucial In Your Business?

RUSHPCB: Navigating Challenges in PCB Design, Manufacturing, and Assembly

Does your company engage in the design, development, and selling of amazing electronic products? Do you incorporate the latest technology in your shipping list? Do you experience difficulties trying to determine the time to spend focusing on the activities associated with the sale and supply of your goods in the market? Luckily, these are some of the major problems facing current electronic and business companies; the problem of Original Equipment Manufacturers (OEMs) in determining whether to outsource part or all of the above problems to a CEM (Contract Electronics Manufacturer) or an retain in-house.

Since we at RUSHPCB understand the challenges many businesses face in designing, manufacturing and selling of electro-mechanical or electronic assemblies, we came up with this blog to help you determine how the above issues fit into your business strategy. Please visit us and learn more about us; one of the best PCB designers, manufacturers and assemblers in the world.

What is a core business activity?

There exist many articles and debates trying to discuss the meaning of core business activity. A business activity is the major source of an organization’s profit and success. This is the reason the company was established. These activities can be simplified into 6 categories; Research and Development (R&D), Procurement, Manufacturing, Test, Outbound Logistics, Sales and Marketing. Please join us as we discuss these activities in detail.

Research and Development (R&D)

Some of the research and development questions you should use to access the viability of your business activity are: Do you have plans of developing new products or enhancing those that you have in the market? Do you have enough resources on your team and is the team experienced to so maintain a healthy competition in the market? Would outsourcing the activity crucial to your business or does it pose a threat to your already existing market property? Do you understand why your customers prefer your products at the expense of others already in the market? What do customers like and how would they be affected by the change of your R&D strategy?

Procurement

Successful management of any supply chain is significant since it helps ensure that the products are built and delivered on time, according to the expectations of the customers and within the specified budget. Many scholars and business entrepreneurs argue that 80% of the lead-time and cost of an electronic assembly is associated with the materials in use. Is it possible to outsource the procurement of the materials to a 3^rd party and maintain a healthy competition? Where are the hidden costs of the business and what additional savings can be realized through the devolution of this activity? It is, therefore, clear that procurement is an important factor and it should be controlled especially if you need to add value to your customers.

Manufacturing

Manufacturing your own electronic devices and assemblies demands our focus which might deviate some of your attention from the core business activity. Moreover, the costs of manufacturing your equipment is costly given you have to consider human resource cost and the costs of operation. However, lack if high quality finished products which can meet the demands of your customers can lead to the dissolution of your business, therefore, the outsourcing of this the manufacturing activity should be handed over to the CEM provider and should be treated professionally.

Companies respond differently in their approach to outsourcing and most of the successful companies in the world have used CEM providers since they were established. So how important is the manufacturing of your company’s products in-house so as to achieve the set objectives and at the same time satisfy your customer’s demands?

Testing

As once stated by Siemens; an electronics provider, “quality is when customers consistently come back to buy your products and customers and customers don’t come back. Most of the customers expect that any of the products they buy from you function from the word go with a very high reliability and low failure rate. If your product fails to satisfy your customers in this utopia, your reputation will be ruined.

There are several levels of product testing with each electronic assembly calling for a different approach. Simple tests are required to ensure that the product switches on and off as expected are necessary. However, if your product calls for complex tests using sophisticatedequipment which are not readily available, careful though is necessary taking into consideration the cost of outsourcing. In this stage, it is critical to ensure that your customers are fully satisfied by your products.

Outbound Logistics

Even if your products are been shipped locally, nationally or all over the world, you rely on your infrastructure to supply the products with minimal delays. With continuous changes in consumer consumption behaviors, it is critical that organizations offer responsive services which are agile enough to meet the changing demand. One should consider the ability of the business to handle the necessity for configure-to-order or build-to-order capabilities.

In order to broaden electronic manufacturing companies, many have come up with procedures and processes which can facilitate the production of products to an embryo level and enable the dynamic adaptation of the products such that they meet the requirements of the customers. We at RUSHPCB have a well-defined logistics procedure which has allowed us to thrive in the competitive PCB world, please Contact Us and interact with our team of experts.

Sales and Marketing

In this stage, one should consider the time and effort spent on the sales and marketing activities. Moreover, the struggle needed to attract new customers and the resultant consequences are important. Comparatively, constant awareness is significant to ensure that your business thrives in the competitive market.

We are aware that this blog post has challenged you more than it has provided solutions to some of the problems. However, our principal aim was to create awareness of the cost and the factors consuming your time in your organization. We recommend that you understand your market better and conduct frequent market research to alert you of any changes in consumer behavior and consumption patterns.

We are specialists in PCB manufacturing, design, assembly and fabrication and we care much about customer satisfaction especially in the products we offer.

Fundamental Characteristics of a High Reliability Printed Circuit Board

Ensuring PCB Reliability: 14 Critical Characteristics for High Performance

Just like in other electronic components, high reliability is the desire and goal for many designers and final users of Printed Circuit Boards (PCBs). Since all the components are mounted on the PCB, it is expected that the PCB delivers some consistency and efficiency over time depending on operating conditions like temperature and humidity levels. Reliability is, therefore, crucial for any PCB regardless of its use and the stage (assembly stage or manufacturing) where it is used. Consequently, it is important to determine the reliability of PCB materials through testing and through observing the data sheets provided by the manufacturer. Moreover, testing the reliability of a PCB is more critical since all the components are mounted on it.

Please join us as we discuss the 14 most important characteristics of a highly reliable PCB. We are experts in the PCB having served millions of customers for over 15 years in PCB assembly, PCB design, PCB fabrication, and PCB manufacturing. Please visit us today at RUSHPCB.CO.UK and get to know the range of products and services we offer.

Hole wall with copper thickness of 25 microns

Importance

Enhances the reliability of a Printed Circuit Board
Improves the resistance of the z-axis expansion where PTHs (Plated Through Holes) are metalized and drilled through the material thickness to form ground connections and form signals.

Risks involved if that is not done

Blow holes or outgassing causes problems in the electrical conductivity during the assembly process (the cell walls break or inner layer separation)
Future possibilities of failure when the PCB is loaded. In this case, we recommend the use of less than 20% copper IPCClass2.

Absence of welding repairs or breaks in line repair

Importance

Adhering to these standards ensure that the circuitry is perfect hence increasing reliability and securing.
No maintenance is required since welding is done perfectly and there are no repairs needed.
Risks like electrical shock due to open circuits are eliminated.
