Flex PCB
Single, double-sided and multilayer polyimide flex circuits for dynamic bending applications.
Overview
Flex circuits use a polyimide substrate that bends repeatedly without cracking the copper, which makes them the standard choice where a board has to move inside the product. Aisler produces single-sided, double-sided and multilayer flex boards with rolled annealed copper for dynamic applications and electrodeposited copper where cost matters more than bend cycles.
Key construction features
- Single-sided, double-sided and multilayer flex construction
- Rolled annealed copper option for high bend-cycle designs
- Coverlay, screen-printed legend and ZIF contact options
- Stiffeners in FR-4, polyimide, aluminium or steel
