Anyone have any experience with flexible circuits? Who have you used to
make them? Can they work from the typical gerber and drill files, same as
a typical board house? In this product, a flex circuit is being considered
due to the curved shape and required thinness of the product. However,
there are lots of parts (chips, LEDs, resistors) that go on the board. Can
you solder parts to a flex circuit without melting the whole thing? I've
generally seen flex circuits used as connecting cables without parts
soldered to them. Can they be used the same as regular boards? If so, how
are parts attached? So far we've used .020 inch thick FR4 board, but that
may be too thick and not flexible enough. Any other ideas? We're using
Advanced Circuits for our normal circuit boards. I see they do flex
(http://www.4pcb.com/quickturn_pcb_flex_design_guidelines.htm), but would
appreciate any comments piclisters may have.

THANKS!

Harold
