Russ, I still don't understand where you're coming from! The chipmaster is a closed loop system...it has a thermal couple. Also, I've got profiles on mine! If you're having problems with a loose nozzle just tighten the four set screws in the bl

Brian, The SRT FPD-W is an older unit that has been successful for a long time. We have used it at BEST with good results. The SRT FPD-W is a very good machine for the uses you mentioned except possibly for the BGAs. I have seen some used for BGA

Does anyone know of a vendor who manufactures pallets for PCB's. I have a couple of boards where the parts are too close to the edge to allow them to be placed in my Pick & Place equipment (nozzle will hit conveyor rail). I know that pallets are made
