Sir: You did not state what kind of screen printer, all the others assumed it was for SMT. We are dealers for ATMA line of screen printing and aux. eqpt. They make a first class, well made press, and are probably the largest in the world now. Over 4,

I believe you've gotten some wise advice about finding a working board rather than attempting repair. If you decide to attempt the repair, checking or replacing the regulators is a reasonable starting point (primary power). The next thing I would d

Dave is correct. Also, you should check the TDS's of the caps and the display before processing to see if they can withstand the process temps, look for a recommended solder profile or info for the manufacturability of the device. On another note,

Tim, The main controller card has a battery on it. Power down the machine and disconnect power. Stick a credit card between the battery and the clip. Hold for at least 60 seconds. Then power back up the machine. Make sure to have yourmod codes writ

We agree with the points made by ScottE above. Additionally, most printers are not heavily loaded. So, you wouldn't have to buy another machine, give-up floor space, purchase and store peculiar tooling, etc. We think Darby does pin transfer. Maybe h
