Omar: I dealt with this so called "hot bar" process also, and you're right; it's neither reliable nor repeatable. The goal was to attach a flex LCD display to another flex circuit. The flex LCD was constructed of resin and conductive silver particl

We've talked about assembling on flex previously. Search the fine SMTnet Archives for background. Issues that come to mind [which is very risky, given that this Saturday morning and last night was at Jimbo's] are: * Use carriers that can flow thoug

Is there a specification in relation to the proximity to features that a Flex circuit should or should not be bent? I am experiencing broken tracks on some flexible circuits which appear to be getting 'flexed' directly adjacent to a soldered joint in

Hi, can you easily remove your board from the pallet?without bending or damage the board? Bryan

I have a 1oz Flex PCB (FPC) that has 2 0.4mm pitch connectors that need to be SMTd and 9 4.5x1.0mm pads that have conductive rubber contacts that are press fitted onto the FPC. The FPC has a one time bend radius of 15.5mm. Image is attached that show

Is printing your concern or placement. I would say both: Printing: At 5 feet and on a flex you better have a really nice fixture to keep everything in check. You'll probably have to hand screen it unless your going to get a dedicated custom continu

For typical small sized circle LED panels, you can simply have a PCB routed to said circle... but when lighting fixtures are sizes 2-3 feet+, and a circular, typically how are the LEDs being spread across the radius? I can see flex LED strips being

A few years back when I was working in a Hybrid company we used carriers machined from aircraft grade aluminum. Its easy to machine on a Mill doesn't bend so easy when mishandled.The thing to know is do your flex circuits sit flat when placed on the
