flex pcb material

Morepcb110 Oct, 2025Business

Flex PCB material typically includes polyimide film as the base substrate due to its heat resistance and flexibility. Copper is laminated onto this base to form conductive traces. Adhesives and coverlays are used for insulation and protection. The material selection affects the board’s flexibility, reliability, and thermal properties, making it essential for high-performance applications like aerospace, medical devices, and compact electronics.
