Flexible PCB Capability for wearable tech with ultra-thin layouts

A flexible PCB typically comprises a polyimide base, adhesive layers, copper traces, a coverlay, and occasionally stiffeners. Thanks to their unique advantages, flex PCBs are increasingly replacing conventional FR4 rigid boards across various applications. Although generally more costly than rigid PCBs, a well-designed flex circuit can reduce weight, simplify assembly, and enhance reliability—making it a valuable option in suitable applications.
