Hello, I have seen the machine doing this problem after being on bypass. Try closing and opening the program again. Maybe the program can have problems, try making it from the beginning. I hope you fixed your problem.

No problem, mate. Just when you look for SPI ask the suppliers this question to be sure.

Rob, I have done it different ways. For the centroid you can do offline CircuitCAM or Valor or even pure Excell. I have used even pick and place machines files to extract data for AOI/SPI programming. These locations and coordinates are already there

Paste release is coming from your stencil, so the checkplot is your best reference.

Cheers Buckcho, thanks for the quick response.

Thanks Evtimov, what are you using out of interest?

Apologies, both, I meant machine.

Hello, Mr. Evtimov is correct. Always use data from stencil. All new SPI machines are pretty easy to operate with. You load stencil data, add you CAD data and then adjust your tolerances accordingly.

HI, we're starting to look into 3D SPI and although we always have stencil data we hardly ever get CAD. Will that prove a big problem or in your experience is it just load the stencil data and compare deposits to expected? Thanks, Rob.

Hello, not at all. Usually you can create programs without CAD data or any text files in my experience. Software just names the pads one by one.
