Hi everyone, here a question for the SMT production engineers... is possible today mount the fine pitch and ultrafine pitch devices (BGA, QFP, CSP), without using the local fiducials, but using the three standard fiducials of row card only? The correct placement precision is still assured? what is the maximum distance to put the local fiducials from the devices body allowed in a layout, to assure the placement precision?
