Introduction to Flexible PCB Materials
In-house laminate storage at Highleap Electronic
What are Flexible PCB Materials?
Flexible PCB materials refer to the specialized substrates and conductive layers used to manufacture flexible printed circuit boards (flex PCBs). These materials allow the circuit to bend, fold, and twist while maintaining electrical performance, making them ideal for applications where space savings, dynamic motion, or unusual form factors are required.
