Hi, In our setup what we usually avoid is to use RoHS BGA on Pb process. But we use sometimes Pb transistor(4~6pins) on RoHS process, no BGA yet have been reported. Its really difficult to say about reability unless you start running some functional

Hi Mefunak, I'd say that the vacuum holding circuit is at fault. If the component is picked OK from the feeder ('vacuum check after pickup' is switched on) then the component is being dropped from the head as the gantry moves to the placement positi
