Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)

this is the order that I use. 1. Teach pcb origin 2. Teach fiducial location 3. dial in vision on fid in mark info. 4. go into mount and verify that the primary image is on in x/y (after perfoming a teach trace condition) and then do any offsetts if
