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

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

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

Ask for board fiducials if you're running arrays. Global fids on the panel do not work well. One handy product we use on flex is "Tacsil". Works well on SMT pallets as well as router operation. It's double sticky stuff that helps hold on to the P
