We expect to see a copper shadow along the edge of pads when soldering boards with organic solderability protection [OSP]. IPC-A-610 has defined this as acceptable for years. During early reflow stages, the flux in paste dissolves the OSP where ther

Ohh, MY! Well, there is a whole block of info that is machine specific. There are 4 things on the main menu, the last one is the system calibrations. It has offsets between the primary reference (if you don't have vision, like mine) then the beam

Sorry everyone...you all seem to be fond of the MyData machines. I just had to make a comment. We had a TP9 for about 2 years. It rarely got used because of the terrible programming interface..When compared to Fuji Flexa and Fuji machines, we reall

The 3000 hours is correct. It was a VERY fast ROI! Back to the discussions on the earlier threads, some of this information is correct. If you exceed the design limitations for keep out requirements and your board tolerances vary, you can have twe

What machines have you worked with previously? Depending on the programming software used, CP6 can be relativly easy to program. CP6 has been a workhorse in the industry for a long time. One the process is set up, maintain the machines acording t
