Here are a couple of suggestions: 1) you could use an FR-4 template with a
cavity in it to hold the flex in a pallet 2) the "floppy end" could be
partially die cut and the rest of the part left tabbed in then you could
snap it/ cut the flex tabs after assembly. Most fixturing does not have to
be complex. If you want to contact me off line you may - we do '000's of
parts like this daily. Regards Steve Kelly

Subject: [TN] Flexible circuit assembly
I need some advice from the assemblers out there.
I'm designing a flex with LEDs/stiffener on half of
it, and exposed rectangular pads at the floppy end.
kind of like:
[O=O=O=O=O=O]=============E
Our typical designs are rigid flex, and I usually
panelize them with break-away rails attached to the
rigid portion, which we remove afterwards.
Maybe I just haven't had my coffee yet, but I can't
think how to panelize a long floppy like the one above?
We don't get the bare boards one-up do we?
There has to be a way to support them for automated
assembly, right? Do you make a fixture or something?
We do NOT want to hand-assemble these!
