Hey all, I just though I give you all a quick update. I managed to get the printer working. The problems were a combination of everything that was discussed here. When I adjusted the GS4 pot for the histogram, I turned the wrong one at first. This t

Good afternoon! We are able to offer some insight into this and fix your issues. A lot of the time, we are able to offer relief from MCSB using profiling. We have a Technical Paper and Application Note for the elimination of them. They can be fou

Brad, Thanks for the info. Now that I have my align data set correctly I'm having this problem. I've greased and realigned until I'm blue in the face. If I do a nozzle change then a function 30, press the nozzle on with my finger and do a functio

Good afternoon! Typically, we normally recommend testing the pot, and adding either Sn/Ag or just Sn to keep it at bay. One nice thing about the solubility of Cu in Sn based alloys is that it should reach a theoretical upper limit of about 0.1%. I

lol! Gonna have to call BS on your search engine complaint. I don't believe you remember all that so you MUST have searched it. Or would I be flattering myself to assume that you took the time to look it up? Nice to hear from you Mr. Fish. I guess

With recent implementation of VOC-Free flux in our shop, we've experienced little solder fines/balls on the above combo of VOC-Free, Water Based, and glossy to semi-glossy mask finish on PCB's. The solder balls show up on close conductor spacings, ~
