WOW, for having never spent more than a drive by with the units and NEVER having set it up or used it, you are a wealth of info. who say's you can't learn anything from the fine smtnet archives? You definately have bean bags on the chin (mind) cause

Daxman, The diagnostic results didn't look very pretty. Especially on the vision x standard deviation. Any time there is an asterisk, that is a bad thing. The failure number for all axis, excetp theta, is .0002. Could need more air flow to the x

Thanks Chris... I do not have the c-tool, but I did make some adjustments to the middle cube when I was calibrating it. Like I said in an earlier post, I cleared the vision offsets in the ap.cal file and adjusted the middle cube until the board alig

Does the table move under the stencil than just sit there doing nothing? there is an optical sensor in the machine near the end of travel, sometimes solder past or dirt gets into it preventing the contact from being made. Another issue I vaguely rec

Giao, These style of MPM's use stepper motors, but no feedback like an encoder or a resolver. In other words all axis positions are assumed after "Reset" of the machine. Because of this style of drive system there is the potential for the vision ga

Hidee Ho Brian! Just like the other Steve, we just bought a SPM too. Our is brand new, and it's a SPM-AV (has vision). The other option we have is a automatic underside stencil cleaner. We're a contract assembler as well, just starting up.

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

SCREENING... 1. Is type 4 paste necessarily required? [No, not unless you are using it for some other purpose.] 2. Is No-Clean Ok to use? [YES] 3. How thin stencil is required? 5 mils? [5 is OK, but I wouldn�t base the decision on the 0201. 6 mil is

Ok guys, I need help. Here's the deal. We're getting micro solder balls under discreets on the bottomside of the board. Here's my set up... MPM screener w/vacuum plate 6 mil metal screen with 90% circular (rounded) apertures 7 mil (measured) past
