We are in the process of validating Silicon 1C55 (thermal cure) conformal coating over Alpha LR725 solder paste. I am looking for anyone who may be using this process, or has been exposed to someone who is doing this process. Our concern is with the

| 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?

I've seen some glass melf's fall off in our facility due to the glue not adhering to the body very well. You could pick these off with your finger after they had cured. (With little or no effort - I never bothered to actually measure the force requir

Just an update on my problem. I spoke to Loctite and they had very few solutions. One thing they suggested to try was to add a thirty-second soak time at 150 degrees to my reflow profile. The problem with that is ramp-soak-spike profiles doesn�t s

Hi: I have seen this problem before. It is caused by improper curing of solder mask by the fab manufacturer. When you run the board thru' wave solder, and then wash the board, you see the problem of white residue. However, when you apply heat, you c
