Rigid PCBs

Rigid Printed Circuit Boards (PCBs) are a type of circuit board characterized by their stiffness and inability to be bent. As the most common type of PCB, they are integral to a wide array of electronic devices. When these PCBs have more than two layers, they are referred to as multilayer PCBs. Constructed from solid, non-flexible substrate materials like fiberglass reinforced epoxy resin (e.g., FR4), rigid PCBs offer superior dimensional stability and enhanced high-frequency performance.

Adding features like cavities, castellations, or flying leads can further enhance the functionality and versatility of rigid PCBs. Cavities are recesses or pockets that can embed components, reducing the overall thickness of the PCB or offering protection to the embedded elements. Castellations are half-plated holes along the edges of the board, allowing for easy soldering onto a PCB. Flying leads are conductors extending beyond the edge of the PCB, offering flexibility during prototyping and debugging stages, as well as in low-volume products.

Proven Technology for a Wide Range of Applications

Widely prevalent, rigid PCBs are essential in everyday electronics like computers and smartphones, as well as in automotive systems, industrial machinery, medical devices, and aerospace technology.

Since its founding in 1981, GS has been at the forefront of rigid PCB manufacturing. Initially focusing on standard multilayer boards, GS has evolved into a leader in producing highly miniaturized PCBs with thin cores and densely placed patterns. Our rigid PCBs are trusted in the most demanding applications, from implants to the Mars Rover.

Advantages of Rigid PCBs

High Layer Count

Rigid PCBs can be constructed with numerous layers, enabling the creation of complex and sophisticated circuit designs.

Structural Strength

Built with solid substrates like fiberglass, rigid PCBs are exceptionally sturdy and can withstand significant mechanical stress. This robustness allows them to support heavy electrical components and serve additional mechanical purposes.

Cost-Effective

The manufacturing processes for rigid boards are well-established and involve fewer steps, resulting in lower manufacturing cost.

Easy Handling

Thanks to their rigidity and stability, rigid PCBs can be handled and reprocessed with ease, significantly reducing the risk of damage during processing.

Conventional Assembly Process

The assembly of components on rigid PCBs follows a standardized and well-established procedure, easily managed by conventional assembly houses, ensuring reliable and efficient production.
