Abstract
A wireless test system is provided for simultaneously performing electrical tests on the opposite sides of a printed circuit board. Specially designed, double-ended pogo pins are utilized to electrically interconnect the top and bottom sides of the board under test to top and bottom printed circuit interface boards, positioned above and below the board being tested, which are electrically interconnected by a flexible printed circuit ribbon. Upwardly projecting test pins on a test and analysis circuit are engaged with contact points on the lower side of the bottom interface board to complete the wireless interconnection between the board being tested and the test and analysis circuit. The double-ended pogo pins are brought into operative engagement with the top and bottom sides of the circuit board being tested by a vacuum-operated actuation system which vertically moves presser bar members to mechanically effect pogo pin engagement with the circuit board being tested without directly exposing the board to the vacuum being created. The wireless system may thus be utilized to test printed circuit boards of either perforate or imperforate construction.
