John, We tape (usually high temp tape) flex to a fixture (usually 0.090" piece of bare FR4). We make an outline on the fixture to get a rough location then use fiducials on the flex for alignment. Print, place, reflow, cool, remove flex. When the

Hi, What would you consider significantly different about lead-free on flex circuits than tin-lead of flex circuits ? Have you published your experiances that you encountered while changing over to lead-free solder paste from a tin-lead paste ? T

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

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

Has anyone ever placed and reflowed a 1.27mm PBGA to 6 mil poly flex bonded to aluminum? If so what is the life expectancy of the solder joints?
