Salut Eric,



You should start with this one http://flexiblecircuittechnology.com/flex4/



An important question : do you own the PCB design? You'll need to have a DfA say in all this!



For a good PCB design, all assembly is in the jigs, like Tan Geok said. You need to keep the flex portion rigid enough, even in the solder paste printer. Good fixture manufacturers (e.g. https://ascenteceng.com/, http://www.dmipallet.com/, http://www.emcgti.com/, http://www.pentagon-ems.com/ ) can give you priceless tooling design support.



Also, pre-assembly baking kinda becomes mandatory, polyimide is way more hygroscopic than FR4.

Objet : [TN] Rigid-Flex PCBA Assembly



Good morning all,



Looks like we'll be getting our hands around a rigid-flex assembly that will need to be produced at our plant in relativity high volume.  I'm referring to PCBA and not the PCB manufacturing.  Although this will be a stimulating challenge that we look forward to, we do not have much experience with this type of board.  Our experience has mainly resided with rigid assemblies.



I'm turning to you this morning in the hopes of getting some direction as how to begin our learning process. Any recommendations on:



- How should we start?



- Do you have any suggested reading?



-Is there training available on this type of assembly process?



-Do you know of any process guru's with a solid experience on PCBA rigid-flex manufacturing that we could contact for guidance?



Any help would be appreciated,



thanks,





EL
