Hello colleagues, I have a very long flex assembly that I run on a SMT carrier by bending assembly in the middle. This crates a curve after reflow, which I want to get rid if. Any ideas.

so you bend it to go in? Can you not let it lay flat? We run flex on carriers, but nothing that large. We also run 48inch long boards, but they are aluminum.

Very strange...I just logged into the internet to come post this very question for all the lurking experts. We have a 16 layer rigid-flex that we have never baked. Our board vendor is expressing concern that we do not perform a pre-bake before assy

Omar: I dealt with this so called "hot bar" process also, and you're right; it's neither reliable nor repeatable. The goal was to attach a flex LCD display to another flex circuit. The flex LCD was constructed of resin and conductive silver particl

:) Yes, I was thinking on this too. Still looking for other options though.

It travels on the SMT carrier bent through all he process.

Are you calibrated to NIST traceable standards?
