Interesting...the very reason we use water soluble paste on some of our boards is for that reason, although I've never been able to get anyone to show me something in print that supports it. It's just what engineering has told me. We currently have

Deja vu! When I read your response I turned around to see if you standing behind me listening to our problem. We currently make about 50 different boards all using no-clean that have no problems, yet this newest boards has a couple of issues that eng

Hi Dave, I looked into the South Coast Air Quality Management District Clean Air Solvent Certification when I was having my problems with VOCs. The problem with the SCAQMD CAS Certification is that it only certifies chemicals as they are found in t

Robert, Someone already mentioned the popcorning phenomena. This would show up as a dome-shaped deformation underneath the component, due to internal delamination around the die area. However what you describe sounds like another moisture-related

The "band wagon" was a corporate decision. The performance issue concerned a communications problem between the line computer and the F5 (f5 locked up in the middle of a PCB). This issue did not show it's ugly head until a month after install. I t

I prefer mine skewered with a remoulade, yum. IPC-A-610 allows component side overhang to the lesser of either up to 25% of the component termination width or up to 25% of the width of the pad for Class 3 devices. Help us understand your problem.

Garth, the short term solution to your problem from our perspective is to rent the suite, train your people, and send it back. This can fit anyone's budget. We try not to have price stand in the way when the training is required. The only danger yo

I am not answering for Techguy2000, but I am chiming in here, I have the same problem. Our resistor packs are ceramic body with no leads, they have a metalized area reminicent of the old castelation leads of year gone by. The lead pitch is 50 mil

I should have been more clear;the temperature that I indicated was measured inside the dispenser cabinet. We setup a very simple system to monitor and maintain the temperature inside the cabinet. By comparing our temperature to our production resul
