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

Dear experts, We are in stage to fix lapse or hold time between pre-bake to reflow process ( SMT ) for flex-rigid PCB, usually for flex pcb , we need to assemble as early as possible once after baking & if not , we can store in humidifier up to some

This is all very interesting. One obsticle I have to live with is I have an adhesive backing applied to the flex circuit before being placed on the pallet. Once gone through the reflow process the flex board goes through a couple of assembly stages a

Jorge, Your description of the process sounds about right. A fixture to hold the flex cable taut (and in a repeatable location) that allows you to paste/place/reflow is essential. As for notes: Be hyper aware of moisture/humidity in regards to

Flex PCB through production

Electronics Forum | Thu Nov 14 12:55:03 EST 2019 | SMTA-Tony

Very late but here's my 2 cents. Will require a custom fixture for every flex or semi-rigid flex. Depending on panel thickness; use 2 tooling hole to fixture on one axis, other tooling holes will have pullers to ensure proper placement. Even with the

BGA Placement on Flex

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
