I can't see the image very well, but from what i see it looks like oxidation. looks like an ENIG finish on the board, possibly a plating issue from the bare board house, thin gold or the nickle is to thick. one other question i would get an answer t

I don't have one of these machines, but what kind of checks are you able to do on the linear encoders? On our Essemtec there is a dedicated diagnostic utility that gives you a plot of the encoder readout showing both the raw readout as a sort of roun

Well everything Graham said with some additional points.. You mention manual printing but very little about your stencil or setup. Everything you have said indicates a very limited budget has been expended, however what you have is an extreme exampl

Yes, most of my fiducials are 1 mm. BUT, you may consider going 1.5mm or even better 2 mm because in my experience PCB manufacturers will NOT check fiducial shape during PCB testing. This goes for fiducials that are placed on panel frame. Fiducilas t

It's been a while but what about the nozzle? Is it still springy? And did you check the part data? At one place our machine would be metric or imperial depending on a visitor from HQ. If you are smashing parts on the board that isn't good and if you
