Awww, blank those fine tech support people at MPM. We know more than they do. Having said that, duh, umm er, please clarify the problem. * Are you concerned about paste squirting through the holes of the side 2 portion of the stencil when you are

We knew they�d make you use those boards, didn�t we? Your boss could be correct, but then again, you might get away with baking. Entek coating thickness is often poorly controlled by fabricators. But if sample boards that you ran are OK, why not g

Why do you want to apply paste by dispensing ? Have you given up all the solutions for your solder paste printing? The cost effective way of using your Cam/Alot is to dispense adhesive. And use your Stencil Printer to apply solder paste. That's what

Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in

Like most things in electronic assembly, this is not astrophysics. People have pasted boards, placed components, turned the board up-side down, run the board through a reflow oven, and generalized about which components: * Fall off the board. * Don

We have customers that are requiring no flux residue left on boards after soldering of non-water washable parts. We currently use Multicore Crystal 502 No-Clean to solder parts that are not washable. Has anyone come up with a good way to remove this

This is a real problem. We have experimented with a number of off the shelf products as well as discussed the issue with a few solder manufacturers. As you are aware IPA or Flux off can make the product look worse. I would discuss with the custome

The quip; All you can get! By the way, worthy answers above, especially Dave F getting a little tied up is good to see, he's always on the money otherwise. But seriously, watch for damage to other components. Example; thru hole's such as radial c

Interesting, we have a SMT division, that caters to the exact scenario you depict... Actually am also trying to determine, a system of answering "high mix, low volume" picture... Just my humble point of view, dun think there is "best" system in th

The biggest concern I have is appearance to customers. You open a cleaning system and it looks worse than your shower after a month of scale buildup. I guess Alpha has two different product to combat this problem. I am going to give them both a
