Methods Of Reducing The Cost Of PCB

Are you in need of a low cost Printed Circuit Board (PCB)? Well, join us as we discuss the possible methods of reducing the cost of any PCB. To begin with, it is crucial to recall that the manufacturing cost of PCB depends on some factors that must be considered during the process of coming up with ant design. Moreover, designs by newbies are not optimized from a standpoint. Many PCB beginners designers especially beginners do not take into consideration the spacing, basic width and many more rules that have effects on the cost and the size of the final design. It is for this reason that we came up with a simple guide on how to reduce PCB cost.  However, in the event of any questions please do not hesitate to contact us, we have a team of qualified staff and are dedicated to overseeing customer satisfaction.

SIZE OF THE BOARD

To begin with, the cost of the board is crucial. The cost is usually proportional to the size of the board. This implies that smaller boards are cheaper than larger boards. Moreover, the costs of the parts are proportional to the size of the board since a larger board might require more components which not only makes it expensive but also makes it lose its aesthetic features. The final product will be expensive such that implementing it for mass production is unrealistic.

ADOPTION OF SURFACE-MOUNT TECHNOLOGY (SMT)

Surface-mount technology; SMT is a strategy of producing an electronic circuit where the components are mounted directly onto the Printed Circuit Board’s surface. Consequently, the cost of soldering the components into place is minimized thus the overall cost of the PCB is reduced.Comparatively, any component that is mounted on the PCB can be easily replaced without having to go through cost procedures like hot gas and infrared to remove the solders from a component. This technique is better that THT since all components on the Printed Circuit Board will be small and more intensive.

REDUCING COMPONENT COUNT

In the same token, if the components on the PCB are very dense, then the routing on the board should have more details and more components will be used. The best way to avoid this is by studying the possible ways of reducing the number of components in use in your design. Intensive research and consultations is needed in the procedure and that is why we at RushPCB are here to help you.

REDUCING THE NUMBER OF LAYERS

On the other hand, the cost of Printed Circuit Boards can be reduced by reducing the number of layers. These layers are made of alternating materials and are laminated together with adhesives and heat thus leading to a single product. These layers are FR4 (fiber glass), copper, solder mask and silkscreen. The best way to reduce the cost of the layers is by designing a PCB that suits your needs and trying to eradicate unnecessary parts of the design. This could lead to lesser layers thus the cost of the board reduces significantly.

DIAMETER OF HOLES AND ANNULAR RINGS

When it comes to the stage of drilling holes and annular rings, we recommend that you come up with holes of bigger diameter so as to reduce the cost of PCB. This is because using smaller holes demands the use of more precise machines which leads to higher cost. On the other hand, the minimum annular ring applies to vias and through-hole pads and is the minimum distance between the pad’s border and the hole’s border.  This is illustrated in the figure below. Some manufacturers will charge you a lot if you need smaller holes (diameters) but we are always fair to our customers, our prices are the best in the market.

USE OF NTHS RATHER THAN BURIED HOLES

On the other hand, buried holes are more costly than NTHs since they have to be drilled at the junctions. Drilling is costly since the end product must be perfect so the drill-bits used in each design are new and the hole might not be perfect and the whole board has to be designed from scratch. Drilling is best done by some experts and it fits those users who need perfect and well-polished Printed Circuit Boards otherwise it is very costly and we recommend the use of NTHs rather than drilling. However, we offer complete boards which are also drilled so you can contact us at RUSHPCB.CO.UK in case you need to do some purchases. We offer the best prices around the globe.Please try us today.

SIZE OF COPPER AND SPACING BETWEEN COPPER OBJECTS

In this case, as the size of copper and the spacing between copper objects decreases, the cost of the Printed Circuit Board increases. This is because printing small objects on copper needs high-precision and small tolerance machines. This translates to more cost thus making the whole procedure expensive especially for low quantity and prototypes production. The physical dimensions of the copper objects are tracks, vias, pads (thru-hole and SMD) and any object that is printed on the copper layer. The spacing between the tracks is always labeled as dT and that between pads dP. We offer boards that are customized to meet your needs. Please visit us today and enjoy our wide variety of PCBs.

SHAPE AND SLOT OF THE BOARD

Lastly, the board’s slots and shapes matters to some of the Printed Circuit fabrication shops. They charge additional costs for any irregular shapes (the normal shapes are rectangles or squares). If the shape of the PCB is not crucial in your design, we recommend the adoption of the square or rectangular shapes so as to reduce the cost.

However, we offer fair prices for our boards and we will advise you on the best way to produce a perfect product from scratch. We have a team of experts who are always ready to serve.
