Hello , any specific insights about printing on flex circuits?

I cannot report having experience with 0201 printing applications on flex circuits. Generally, I would be concerned with handling of the flex substrate. A carefully designed vacuum capable custom tooling fixture would likely be required to ensure p

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 John, We use Spray mount adhesive on durastone pallets, then kapton tape on the egdes. We have produced upto 25K flexi PCB's a day with this method. The trick is to get just the right amount on the pallet, to maintain tackiness. Cheers, Rob.

....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

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

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
