| 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?

My printer handles 1500mm stencil, so no, 4 ft boards print ok. If you are bending the board for the oven, does that mean your printer and PnP handle the full length?

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

We don�t use this glue. What does Heraeus say about your condensate? [I'm With the previous poster. Your condensate sounds like goop from NC flux not glue.] How to clean out a 3 meter length of chimney? Depends on your tolerance for pain * Take

Grant has a good idea, we started that way also. We made a tank out of stainless steel with copper tube coils about 18" off the bottom. Circulate cold water through the tubes to condense the vapor to keep the loss down. We used electric burners under

| I have a severe problem with flux residue being drawn up the vent ducts of my reflow oven. This residue reaches a critical mass then begins to flow down the ducts and becomes very messy. I run a no-clean process and use IR oven. Has anyone else o

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

Did I mention, we tried to use the same WS flux formulae to brush-cover the affected flex-PCB pads, and subject it to another round of water-wash, followed by oven-baking, and it still doesn't help abit? Oven bake : 100 deg-C, approx 15~30mins (manu
