Hi, how to ensure flexible boards do not warp after reflow and still remain flat for subsequent operations. What is the best way to hold and transport these strips from one process to another. Thanks!

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

These notes are from ~2005-6. I remember pictures of the pallets and the reliefs on the stencil. Bob may still have his presentation online. Check his site.

Polymide is like a sponge and absorbs moisture much faster than rigid substrates. Pre-bake your substrate for 2-4 hours at 125C and perform your soldering within 1 shift thereafter or seal in moisture barrier bags.

If your washing them in-line, heavy silicon mesh works good in cages to keep them from flying around.

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
