Hey all, I am currently looking into switching from using Alcohol in our screen cleaner to Zestron SD301. I am confident that it will clean our stencils better, but the cost of Zestron is 3 times that of alcohol. Has anybody done any studies o

Hi Scott - No clean assemblies have a very low tolerance for processing residues, and long term reliability is compromised if residues from incoming bare boards, components, or un-solublized flux residues are not dealt with. It is critical to contro

I don't know exactly what you are hoping to learn from the ROSE tester, but if you want some information on how ROSE testing correlates (or doesn't corrlate) to actual board cleanliness and long term performance, take a look at a correlation study we

I have worked w/ the GSI SVS 8200's. They seem to do a pretty decent job, but, they are a "bottleneck" on my lines. I hope you are using good screen printers, because they WILL find the slightest "defect". About 75% of our failures are actually fa
