ABSTRACT:
An improved printed circuit board inspection apparatus in which its inspection probes are made to contact with a selected part or printed circuit section on a printed circuit board for making an inspection on the selected part or printed circuit section in terms of their performances or functions. The printed circuit board inspection apparatus uses two guide sets each having at least one pair of inspection probes and driving means to drive said inspection probes in X- and Y-directions to selected coordinate positions in the printed circuit board. A central processing unit controls said driving means so that the inspection probes of one guide set are used to make an inspection at a selected coordinated position while the other inspection probes are traveling to another selected coordinate position for subsequent inspection according to a predetermined program.
