Disclosed is a design for a wiping pogo to clean a plugged device on a printed circuit board.

Printed circuit boards (PCBs) use a bed-of nails-connector system to temporarily connect the tester to the board. Each nail head is soldered to the test circuit board; the other end of the nail contacts a test feature on the board under test. To make a good, low-resistance contact, the nail tip must dig through solder flux residue and any corrosion product layers on the board. Contact wiping action is commonly used as a means to wipe.
The novel contribution is a design for a wiping pogo. The wiping pogo contains a slotted housing that receives a pin connected to the pogo head. As the head actuates, the pin rides in the slotted housing causing a rotation motion. It is during this rotation that the wiping of the device being plugged occurs. The wiping motion removes or breaks through corrosion and allows an electrical connection.
