How should you select the materials for your PCB
The materials used to manufacture Printed Circuit Boards (PCB) encompass a set of insulating/dielectric and conductive materials used to construct circuit board interconnects. There is an extensive selection of material choices to choose from to meet varying performance and budget requirements. The type of material used to manufacture a PCB is a key factor in the durability and functionality of the PCB assembly. Selecting the correct PCB material requires a knowledge of the available materials and their physical characteristics and how they align with the required functionality of the board.
Types of Printed Circuit BoardsThere are 4 main types of PCBs:
- rigid – a solid, inflexible, single or double-sided PCB
- flexible (flex) – often used when the PCB cannot be confined to a single plane or sits a non-planar position
- rigid-flex – is a combination of rigid and flex PCBs, where the flex board is joined with a rigid board(s)
- high-frequency – these are PCBs that are usually used in applications requiring special signal transmission between a target and a receiver.
