This is all very interesting. One obsticle I have to live with is I have an adhesive backing applied to the flex circuit before being placed on the pallet. Once gone through the reflow process the flex board goes through a couple of assembly stages a

We are doing what I believe is unique from everyone else. We are using a .010 thick flex circuit board populated with the usual components, sot-23, caps, resistors,etc. It is mountd to a carrier plate with the edges taped down but I am having troubl

Hi Dave, 3M� Spray 75 Repositionable 500 ml was the last we used due to a bright spark in purchasing, but production didn't get on with it too well. The only one that really gives us good consistant performance was the original 400ml Spraymount a

Things to consider are: * Thermal expansion characteristics of you flex and your pallet should be better matched. We use G-10. * Placement of your two sided tape should be better, more uniformly distributed. We run strips the length of the flex that

....not unique. But tough as hell! I build flex assemblies for a major P&P equipment manufacturer. Some are pure flex, most are ridgid flex. And of course, why put fiducials on the boards to help the process (why God, why me?) We use pallets and
