Capabilities
Almost all electronic devices use either rigid or flexible PCBs or Printed Circuit Boards. As the name suggests, rigid PCBs are stiff and do not flex or bend as flexible boards do. The electronic industry, automotive, military, aerospace, telecommunications, and many others use rigid PCBs extensively. Rush PCB is a leading rigid PCB manufacturer in the UK and Europe, offering precision-engineered printed circuit boards for a wide range of industries. From PCB prototyping to full-scale production, we deliver reliable, high-performance circuit boards with fast turnaround times and consistent quality.
The Need for Rigid PCBs
Rigid PCBs command more than 70% of the total market share of all types of PCBs manufactured all over the world. One of the biggest advantages of rigid PCBs is their rigid, permanent shape. Primarily, they are non-flexible, and it is impossible to bend them or force them out of shape. Another advantage is that rigid PCBs can be made multilayered if necessary. The rigidity of the boards is due to the substrate materials that manufacturers use to construct them.
Rigid PCBs can use both types of components—through-hole and surface mount. For through-hole devices, it is necessary to drill the board to allow mounting of the components. This is not necessary when using SMCs or surface-mount components. This allows close packing of SMCs, leading to a much higher component density. That is why almost all industries now prefer using SMCs to manufacture their assemblies.
The rigid PCB provides a solid support for the electronic components mounted on it. Copper traces on the board provide the interconnections between components necessary to allow the circuit to function as intended. For multilayered boards, vias provide the interconnections between different layers.
Rigid PCB Features
Basic characteristics of rigid PCBs include:
- High Stiffness or Rigidity — does not bend or flex easily
- Good Thermal Stability — able to operate over wide temperature ranges
- High Dimensional Stability — does not change shape easily
- Good Electrical Insulation — the substrate is a good electrical insulator
- Multi-layering Capability — the board can have multiple layers
- High Voltage and Current Capability — the substrate can withstand high voltages and currents without failure.

Rush PCB Rigid PCB Manufacturing Service
At Rush PCB UK, we provide many useful manufacturing services for our rigid PCBs. These include:
PCB Design
We design all types of simple to complex rigid PCBs, whether they are single-layered, double-layered, or multi-layered. We convert your schematic diagrams into layouts using the latest PCB design software, consulting with you for the best layout, and taking care of DFM or Design for Manufacturing requirements. We also follow any PCB standard you want us to, and take your approval before finalizing the design. We can design your PCBs for through-hole components, surface-mount components, or mixed designs.
If your board is small, we can penalize the design so it forms a standard size suitable for fabrication and assembly. After assembly, we use laser cutters to separate the panel into individual boards.
Material Selection
Although the most popular substrate for rigid PCBs is FR4, we can use any other substrate material for your PCB design. By proper selection of the substrate material, we help our customers to design any high-frequency or high-speed PCB.
PCB Fabrication
Using your certified design and the material selected by you, we fabricate the rigid printed circuit board to your complete satisfaction. Whether this board is single-layer, double-layer or multi-layered, we use our latest technology to fabricate very high-quality boards. Our in-process quality inspection methods ensure that your board achieves the quality and perfection it deserves. For this, we use AOI or automated optical inspection methods.
Bare PCB Testing
We have a complete sequence of testing for your boards after fabrication. We ensure there are no open, shorts, or any other damage in your boards.
In-Circuit Testing
Once the Assembly and soldering are done, we also undertake to test the boards using either in-circuit testers or Flying probes. This ensures that all your boards will work as intended.
Types of Rigid PCBs
At Rush PCB UK, we offer many types of rigid PCBs to our customers. Some popular types of our rigid PCBs are:
Metal Core PCBs
These boards have a metal core to improve the thermal conductivity. They are mostly required for high-power LED lighting applications.
High-Speed PCBs
Operating at high speeds and frequencies, these boards use specialized substrates like Arlon, Teflon, and Rogers.
High-Tg PCBs
For applications that must withstand high temperatures, high-tg PCBs use specialized substrates with high glass transition temperatures.
Heavy Copper PCBs
Hervy copper PCBs use thicker than normal copper traces to carry higher currents without heating. They are very helpful for applications that must handle higher power and currents than normal.
Quality Standards & Certifications
We follow internationally recognized manufacturing standards to ensure consistent quality:
- IPC standards for PCB fabrication and assembly
- ISO-certified manufacturing processes
- RoHS-compliant materials
- Strict quality control and inspection procedures

Frequently Asked Questions
Rigid printed circuit boards are used in almost all types of electronic equipment. For example, they are used in commercial and consumer electronic equipment like audio amplifiers, televisions, communication sets, air conditioners, personal computers, desktop computers, automobiles, and many more.
Some important specifications for rigid PCBs include the material of which they are made (substrates), number of layers, total thickness, copper weight, physical dimensions, surface finish, and whether they are RoHS or not.
The first step in our manufacturing process involves obtaining the films for all the layers and procuring the substrate material. Broadly, we use the following steps:
- We prepare the core of the board using a suitable glass-epoxy layer and sandwich it with the specified copper clad substrate material.
- We then transfer the innermost circuit design on the copper layers using lithographic methods.
- We then drill the necessary holes for vias and through hole components.
- Unwanted copper is then removed by etching.
- We electroplate the core and the holes to form the vias.
- Subsequent layers of copper clad material are prepared, and circuit design for these layers are transferred.
- We then drill these layers and etch them.
- After plating them to prepare the vias, we bond the individual layers to the core.
- The entire board is covered with solder resist leaving only the pads to be soldered.
- These pads are then covered with surface finish to protect the exposed copper from tarnishing.
- Any text to be written on the PCB is screen printed with a silk screen.
- PCBs are then packed and shipped.
The main advantage of rigid PCBs is their rigidity, which prevents them from flexing and bending during transportation and movement. While other types of PCBs might change their dimensions and shape with environmental change like temperature, rigid PCBs are more stable.
As evidenced by their name, rigid PCBs can be adapted to specific industry needs. Some examples of rigid PCB solutions are:
Aerospace and Defense — The harsh environment and critical applications in these industries require PCBs with extreme reliability and stability.
Radar, Communications, and Electronic Warfare — Equipment in these industries use high-frequency PCBs and require high signal integrity for their operation.
Medical Devices — Most implants and wearable devices require high-density but compact PCBs, that must perform reliably and consistently. Some medical applications also require boards that are biocompatible.
Automotive Industry — This industry requires the most high-precision manufacturing, and highly durable PCBs capable of withstanding intense vibrations, large temperature fluctuations, and high levels of humidity. Parts closer to the engine must be capable of withstanding high temperatures.
Industrial Automation — Industrial environments can often be harsh, and PCBs for industrial automation must be durable and robust. Some industrial machinery requires PCBs capable of handling high currents and high voltages.
Lighting Industry — In most parts of the world, lights are primarily high-power LED based. Although LEDs are highly efficient, they do produce substantial amounts of heat when operating. Metal core PCBs are very useful for use in the lighting industry as they can effectively remove heat from the LEDs to allow them to operate without damage.
