Abstract

A widely-used procedure in testing printed-circuit boards is to place them on what is called a 'bed-of-nails' fixture, which allows electrical contact to be made simultaneously to every component on the board. The problem with the bed of nails fixture, however, is that all too often contact with the conductors on the board is not reliable, so that a substantial number of good boards are rejected as faulty. This results in a waste of time and money, trying to find faults which do not in fact exist.
