Hi Greg, I have the same problem over here in Belgium. I have been looking to rent an X-ray but for the moment I only found Glenbrook as a possible source. So I would be very interested if you find any alternative. Furthermore I am also interested i

| Hopefully, everybody suffers from solderability of SOT-23 devices and I would like to know how everybody else resolves this problem. | Historically, here, we have always gone for 6 thou stencils. I found that going to an 8 thou stencil improved the

Graham, I think your problem is unrelated to the previous message. I believe there may be a problem in the Forum Application, that is causing this problem. I have known about it for a while, but not exactly sure what is causing it. If you could pro

All y'all BACKGROUND. How many times do you see folks come to work all painted-up and then by the time first break comes, the lipstick, eye liner, and who knows what else are gone and they�re heading for the facilities to "freshen-up." I wonder

We are in the same position like you. We are in a tug-of-war with our QA with regards to this process. Their reason is that the machine is used for quality purposes which is to verify BGA solder quality so it must be under Quality. From my experience

I'm sorry, Dave - I didn't make myself very clear. Yes, this space (not really a "gap") is filled with solid solder. For instance, if you place a gull-wing component in solder paste, after reflow, there will probably be a thin film of solidied solder

0402 tombstoning and dewetting on QFP256 trade-off

Just my opinion but it look's like your doing a great job. i would try another paste. I'm somewhat lucky that we get to use OA's. If your stuck using the no-cleans they are so tempermental. (The nitrogen is making up for the poor paste) Your de-wetti
