| I am looking for information on reflow temps for a flex board. There is only one 6 pin IC but the board has a 3M double sided tape. | Is it possible to reflow without damaging the tape. Any suggestions? Do you have a profiler for your reflow oven?

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

IPC-FA-251 recommends 121*C for 30-60 minutes for 1 and 2 flex layer circuits. A rigid flex can take easily an hour per layer depending on the construction.

I have a customer that is requesting their flex circuit be conformally coated. Is this something that is done? Which coating would stand up to the stresses of flexing? Wouldn't that put stress on the components? Thanks! Shannon

At a previous job I had been taught that when reflow soldering polyimide flex circuits, it was necessary to pre-bake them before reflow soldering to prevent delamination. Our procedures said that there must be a 1hr bake prior to reflow, and the flex

| I need advise on how can bonding of ICs to flex foil be done. | The pitch of bonding is between 70 to 100 microns and the foil thickness is from 25 to 35 microns. | | Anyone, please enlighted what kind of bonding technology (thermo-sonic maybe), a

We had a contract in house that included a flex board which required an 18 hour bake at 105 degrees. The other brds got along fine with 2 hours, but the flex board would delaminate until we went to this long bake. I don't know how the engineer came

Bend it for mounting，if it can't be mounted by bending assembly. you can choose other pick and place machine which can handle this flex pcb. How long is this flex board? And do you use jigs when reflow? Could you please send a picture of the jig yo
