• Fills pinning machine hopper with metal pins.
• Reads work orders to determine specified pcb's.
• Positions pcb's on bed of machine.
• Turns machine levers and handwheels to adjust, align, and hold pcb's for drilling and pinning.
• Activates machine that drills pinning holes and inserts pins into pcb's to stabilise pcb's during numerical-controlled drilling of component mounting holes.
• Stacks pinned pcb's for transfer to next work station.
