Good question, the answer as of right now is yes. Our machine is only able to go down to 0402 parts before the surface tension of the solder begins to cause issues with maintaining the placement position of the part on the nozzle. However, we are dev

When I try to load a board in our MPM UP2000 HiE I get the following error "Z axis software limit". The Z axis will move up and down freely, I re-calibrated it and reprogrammed the board and the error continues. Has anyone else run into this issue an

Check/reseat all connections on axis driver card and from driver card to step motor. On older MpM's it is common to get a bad connection on the connector for axis driver power and blow components on your driver board. Reseating these connectors mig

Davef is right on as usual. We are doing exactly what you do. Some smt with no clean paste then the plate through connectors on our selective solder machine using water soluble flux. We then clean with a ultrasonic water process. We do see the re

I'd think about database structure and programming aspects as well. I'm cleaning up an implementation where the parts were taught as they appeared to the AOI programmer irrespective of the Pick & Place data/libraries. Lots of rotation fixes, parts
