Abstract:
An inspection apparatus for determining conductivity between and among inspection points on a printed circuit board, said apparatus comprising:a plurality of probes arranged in a pre-determined basic grid pattern;a translator board including a first set of terminals arranged in the same pattern as that of the probes and a second set of terminals arranged in the same pattern as that of the inspection points on a printed circuit board to be inspected, the first set of terminals being respectively electrically interconnected with corresponding terminals of the second set, the translator board being exchangeably mounted in the apparatus;interconnecting pins for electrically interconnecting the probes with corresponding terminals of the first set of the terminals of the translator board;a supporting board including a plurality of through-holes arranged in a predetermined basic grid pattern for supporting the interconnecting pins, each head of the interconnecting pins being enlarged so as to be held on the upper side of the supporting board and a diameter of each through-hole being larger than a diameter of the interconnecting pin, and a member for biasing the supporting board to displace the tips of the interconnecting pins from the translator board while the apparatus is at rest.
