Abstract

PURPOSE: To enable the inspection of continuity, insulation and patterning of a high density printed board, by contacting and moving the specified spring probe unit on the front and back side of a printed board to be inspected.
CONSTITUTION: At the region almost equal to the circuit forming plane of an inspected printed board 12, spring probe units 10, 11 having a number of spring probes corresponding to all the lattices which are a multiple of the basic lattices of through-hole type of inspected printed board, are contacted on the surface and the back surface of the board 12 at the same time. Next, the judgement of propriety of the patterns 2W8 is made, and the units 10, 11 are intermittently fed in the pitch of the basic lattices of through-hole formation of inspected printed board so that an arbitrary two-point on the basic lattices is positioned to be contacted at the same time on the two spring probes of the units 10 and 11.
