Printed Circuit Board Laminate & Pregreg Materials
PCB laminates are made of these three basic building blocks:
- resin
- glass
- copper
PCB designers face many choices when it comes to selecting the PCB laminate/substrate. The right choice is critical to ensure the optimal operation of the board and minimal signal loss.
