Hi, SMTnetters � Does anyone have any information on waffle trays, is there an IPC guideline for the use of these? I am experiencing a universal GSM dumping trays with parts still in the trays and I suspect the tray data will require amending if the

Hi There Just set your Tray Pickup X and Y to -1. This way, the PTF wont reject your tray but you will need to remove manually the empty tray. It's a little bit longer but you wont have any broken pieces. Seeya! Steven
