Good Afternoon, How is the stiffener adheared? If it is laminated to the flex, it may help you with the surface planarity through reflow. If it put on with PSA, it may cause more problems then it would solve. PSA gets soft through the reflow. It may

Generic fabs should not require baking. Some special cases like teflon and flex circuits take moisture very well, they often continue to require a trip to the oven. Best wishes, Boca

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

So is it fair to say that on a moisture laden double sided flex circuit you could see an increase in tombstoning on the 2nd pass due to warpage created by delamination? In other words a 0603 for instance could tombstone due to the delaminated surfac

Adam, What is the pad finish on the flex circuit? Is this the only component that you are having problems with? (on this Flex)If this is the only problem area on the flex (assuming there is more than one component)then that would lead me towards the

I'm with Russ on this one. Had a similar problem with a flex circuit that used gold contacts into a ZIF connector on a ridged PCB. After may test I finally convinced the customer to do some test on the ZIF connector. The end result was flux contam
