Abstract

In printers used in word-processing equipment, particularly when these printers are fan-cooled, foreign particles, such as paper dust contamination of the contacts, between printed circuit boards and the mother boards into which printed circuit boards are inserted sometimes present a problem. Since the current flow in the contacts between the printed circuit boards and the mother boards is very low, any particles or dust which interferes with the complete contact presents a problem. This problem becomes particularly pronounced when it is necessary on some occasions to remove and reinsert the circuit board into the mother board.
