I'd start by checking and reteaching the nozzles (this is automatic, it'll measure the nozzle length and vacuum values for each nozzle). After that double check the value you have entered for the PCB thickness as this will impact where the machine t

This happens with either old tape, the cover tape doesn't stay sealed on the left side, or is the seal is too far to the right, the knife lifts the cover tape. There isn't much you can do in this case. Your choices are: switch the component into an A
