We've not seen "pick problems". We've seen "release after pick problems" caused by adhesive on components, recently. Could be the came thing, though.

Howdy Y'all, I have seen a problem lately with getting the 0402 parts out of the tape and onto a PCB. We are using Universal HSPs with 8 X 2mm feeders in good condition. The components are manufactured by Rohm. The tape and components appear to b
