You don't necessarily have to bake the flex circuits, but you do have to worry about moisture. Polyimide is very hydroscopic, and depending on the flex construction, any moisture in the product can lead to delamination. Adhesive based flex circuits

Is there a specification in relation to the proximity to features that a Flex circuit should or should not be bent? I am experiencing broken tracks on some flexible circuits which appear to be getting 'flexed' directly adjacent to a soldered joint in

Another thing to look out for... Flex circuits, if not fixtured properly tend to move around and, well, "flex" during screen printing. At another place I worked, we fixtured the flex circuit on a SMT pallet on the corner tooling pins to "stretch"

The SMT MFG Process for Flex circuits is relatively the same as traditional SMT process, the key is your PCB supplier. The good flex circuit shops will supply the circuits in a rigid carrier or if Rigid/Flex the supplier will create a support structu

Hi, We are placing a Surface Mount connector on a flex circuit, we are planing on using SMT carriers to support the flex through the SMT process. Underneath the connector a stiffener needs to be adhere, I'm not sure if we should have the flex manu

I agree with the local fids concept. This is usually a problem since the flex will most likely not have fids. However if your components are 50-mil pitch and 1206 or larger, you could use tooling holes to align the flex circuits when they are attach
