hi all, could someone have an idea, would it be the best method to attach a flex cable to a pcb. right now, we are using a hot bar to solder the flex to the pcb, but we are having troubles with this method. the process is no regular all the time a

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

I agree with the two other replies. Left alone, it is a defect. If it's just excess adhesive or coating, you can use IPC-7711/7721 'Rework, Modification and Repair of Electronic Assemblies' for guidance on removing. Section 2.3.1 explains how to te

We don't know dip a about rigid flex. Flexdude wrote "Hot-Bar Soldering, Attaching Flex Circuits Directly To Rigid Boards" [http://www.flexdude.com/Back%20Issues/FCN11-00A.PDF ]. It may help you get started while waiting for others reply. We have n

I am working on a new product that has a flex circuit attached to an 8 layer motherboard. There are 25+/- connections. I am investigating hot bar soldering vs ACF (conductive film) to make the attachment. I am looking for literature/papers/experim

DaveF, What is your prediction if one tries to put a solder iron to it? Will the component bridge? I know hot-bar soldering is more common for things like Flex Circuits (with silver-filling epoxy), etc. and not so much for things where standard so

Yes I agree with Emil that the Jig/Fixture design is crucial for alignment. The hot-bar machine I worked with came with a digital camera and monitor to aid with alignment. Other than that, the right profile (heat, pressure and dwell), and a good fl

Hot bar soldering or hot bar bonding with ACF is widely used for your applications. A company I represent can assist you; Fancort Industries.
