We have never coated flexible circuits, although these guys apparently do as a part of their FC fabrication services: https://gcaflex.com/why-is-conformal-coating-important-for-flex-printed-circuit-boards/

Hi I don't see any answers so let me ask a question so even if I don't pop back in others will do their best. Is FPC (Flexible Printed Circuit) or is it something else. I only know cause I have been into that flexible circuits. YiEngr, MA/NY DDav

Several methods are available for singulating or extricating individual flexible circuits from a processed panel; this discussion of the topic applies to all types of flexible circuits. In general, the methods for singulating flex circuits can be bra

"Flexible Circuit Technology" by Joseph Fjelstad is a good place to start. If you get into production, you will encounter all kinds of new challenges with print quality, fid reads, inconsistent HASL, tooling and using creative P&P programming to mak

Local customer is looking for ways to depanelize very small flexible circuits after assembly. Perhaps shearing as opposed to a router would make sense. Any recommendations on manufacturers for such technology? Volume is around 100,000 pieces per mont

When we hear the words 'flexible circuit' and 'delamination' in the same sentence, we think: * Excessive reflow temperature. * Entrapped moisture. Boardhouse: I hope this is a step towards redemption.

Right, but these contacts have up to 36V running through it 20 minutes at a time unlike your wedding ring when you are swimming. If you take a look at the picture I posted in the last comment, that is what we are seeing over the course of use.
