Continuing the line of Michael's, the previous poster, comments ... The more Krispy Kremes, the better. Yeth!!! The more beer, the better. Yeth!!! The more epoxy, the better. Uh, I don think so!!! We look at this from a papa bear, mama bear, bab

I would bet that it is a SMT adhesive used to ensure that the BGA does not move during a secoindary reflow prcess. this glue is easily removed with a soldering iron. Russ

Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition

Hello Everyone! I have encountered a situation where I have surface mount components on the backside of the board and I need to wave all the through hole leads on the backside as well. Can this be done? I thought of the possibility of adhering the

Do both sides of that board contain larger IC's and other large components or just one side?? If just one side contains large components, try running the side with the smaller components first, and then run the other side last. If that doesn't work

Hello KA, When producing in kind of PCB product you have to base much of your decision on cost effectiveness, time, and quality. In order to get the best of all three you have to decide which you want to be your top priority. By adding an epoxy to

KA, Joshua makes a good point. A wave solder fixture will allow you to process your double-sided boards without having to add the epoxy step. The one time fixed cost of a fixture is quickly offset by the time that you save by not gluing your SMT.

I did this at one point and found that the handleing is critical. What usually happened is that two of the PCBs would touch and the edge of one would scrape the parts off the other. I tried a couple of different epoxys and ended up with a CIBA prod
