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

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

....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

vshan, We were using pallets (delmat with cavities for the flex) We put stips of double sided Kapton tape in the critical areas. The tape held up to the heat and kept the circuit flat for the QFP's and BGA's. We based our assembly process for this c

vshan, Good Morning. I used to work for a flex house and was responsible for the SMT assembly area. What is your question? Thanks Chris

I have customers populating LEDs on flex PCBs (with Aluminum support plates) with sizes up to 1,200mm (say 4ft) even on old Philips/Assembleon Topaz machines. What components are you planning to assemble on your flex PCBs?

I am interested in performing SMT Assembly on flex boards that would be a couple of inches wide but 2 to 5 feet long. Obviously quite a challenge. I would like to hear from anyone that may have seen anything similar done, or at least has an idea of h

There is also a good reference book on flexible circuits from Joe Fjelstad. http://flexiblecircuittechnology.com/flex4/ This book covers everything from creating the flex circuitry itself to the assembly of flex circuits. Also, roll-to-roll assemb

Hi Guys, I´m looking for information about processing smt components on flexible printed circuits (printing, SMD assembly,reflow soldering and laser cuting). These flexible circuits comes from a roll of 300 mm width. I found some information about ro

Hi, Since you're looking information about flexible printed circuits,a book entitled "Printed Circuit Boards R. S. Khandpur" could give you lot of information about flex circuits from Design, Fabrication, and Assembly Phase. The book contains compr
