WHM-281SD3BM push-up stacker
Available on backorder
Our push-up stackers are designed to move individual bare PCBs from the production line through an integral flat-belt-type conveyor and place them into a stack (up to 400pcs max). This machine can accommodate boards from 0.6 mm to 2.5 mm thick and includes automatic stack height sensing. A pass-through function allows other equipment, such as a magazine unloader, to be installed at the exit for double-sided board storage.
