Load Bare Boards for Assembly

The Manncorp DL350W-BT Drop Stack/Bare Board Loader is designed to take individual bare PCBs (up to 400 mm long x 350 mm wide) from the bottom of a stack (up to 200 mm high) and to feed them into the production line from an integral edge-belt-type conveyor.

The Drop Stack/Bare Board Loader accommodates boards from 0.4 mm to 2.5 mm thick and includes automatic stack height sensing and alarm.

Pass-Through Mode for Double-Sided Assembly

A pass-through function allows other equipment, such as a magazine loader, to be installed at the Drop Stack/Bare Board Loader DL-350W-BT input for double-sided board assembly. When a line is set up this way, the DL-350W-BT would be used to send bare boards through the line for first-side assembly. When the assembled boards are returned to the line for second-side assembly, the Drop Stack/Bare Board Loader would act as a basic pass-through/transport conveyor.

Systems for PCB widths larger than 350 mm are available upon special request. Please contact Manncorp for pricing.
