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

There are lots of examples of changing a parameter in one direction to fix one issue causes a different problem. Once I asked a layout engineer to adjust thermal relief for through hole parts. First he said ok but a day later he said that he couldn't

I get a Timeout waiting for nozzle changer vacuum buildup failure every time I go to run my 1998 GSMx machine. The problems seems to be that once in a while (it seems to be random) the spindle does not line up exactly in the center of the nozzle cha

Hi All, We are being intermittently challenged by a .5mm pitch uBGA paste release issue. We don't build with many of these so don't have a lot of history here. We've gone through 3 different stencil designs and the most consistent performer was 4 m

In trying to have things run smoothly with placement, I have to do a lot of theta adjustment to get the rotation right during placement. Even if the part looks good on the PnP machine screen sometimes it places differently than what is shown. If I u

As Evitomov says, provided you check everything is setup correctly there should be no issue. There can be some variation between manufacturers as to how they package certain components. For example 2512 resistors are usually in 12mm tape with a 4mm s

In most cases PnP files are all that is needed for SMT program generation. BUT, it depends on origin reference of this data as exported to PnP and could be off in X,Y and rotation of image pending when PnP Data is exported. Also Rotation of parts

At the moment we do it like this: We get .csv or .txt pick and place file and .csv or excel bom file. Then I verify every single placement manualy with BOM and delete placements that are not listed on BOM. (Yes, you are right, I do it for 30 placeme
