We are currently comparing the Fuji QP2 machine to the Universal GSM. The primary use will be for QFP's down to .4 mm pitch and for 300+I/O BGAs. My initial input has been that you spend alot of time tweeking PD's on the QP because the vision syste

Jerry, I have been using the QP in a Proto and Production environment for about a Year and once the PD is Created(which may take some time) and vision processes. I rarely ever need to make further changes. As far as BGA Pd's. They are a Little
