SMT Research has offered to sell us 0.4mm nozzles for tests. Even if the camera worked with the nozzles and parts (which I doubt) I don't think the CP4 has the x-y accuracy to place 0201s well. We'll see, they are ordering the nozzles, test parts and
COT specializes in high quality SMT nozzles and consumables for pick and place machines. We provide special engineering design service of custom nozzles for those unique and odd components.
