Ultra-soft FPC

Because wiring in a limited amount of space is necessary in order to accommodate smaller electronics appliances, there are many cases where assembly efficiency decreases due to the spring-back property of conventional FPCs. We can supply FPC of low spring-back property, which solves this problem, by using coverlay made of photosensitive polyimide resin or ultra-thin polyimide film coverlay.


Feature 1

Low Spring-back Property

This FPC offers good assembly efficiency because the spring-back property is smaller than that of conventional coverlay films of thickness up to 12.5μm. Also, this FPC can maintain a required shape when using a photosensitive polyimide coverlay(PICL).

Low Spring-back Property
Feature 2

Simplified Process

Use of a photosensitive coverlay shortens production lead-time and reduces costs because the process can be simplified compared to that for conventional coverlay process. Furthermore, tooling costs can be reduced because coverlay punching becomes unnecessary.
