I'm just throwing this out there, but is anybody manufacturing large footprint flex circuit PCBs? (I'm talking assemblies 18-36" in length) We're in the midst of quoting a new opportunity that involves several flex circuits of this size. Currently o

just out of curiousity, why the special nitrogen cabinet concerns for gold plated flex PCB? common "myth/fact" is gold is an "inert" coating layer that is not going to react with room environment conditions *that much?*. Am learning here, so would ap

I hate to answer a question with a question but what are the particular effects of moisture absorption in a flex circuit?

You might try assembly carrier tape such as Tacsil on your fixtures. Beware - arrays are very diffult to run in SMT flex unless you have no fine pitch.

Yes, they should be baked prior. We pre-bake all polyimide fabs, flex or not. They are prone to delam.

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

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

Anyone have ideas how to get MIL 50884 Qualification?. We are a small/mid sized Flex, rigid-flex circuit shop in Canada considering MIL Qualification. Is there any web site that we could check out? any advice is appreciated. thank you. Regards Kc.
