Abstract
The invention relates to a module for a parallel tester for the testing of circuit boards, and to a parallel tester comprising such modules. The modules have circuit boards standing at right-angles to the plane of the basic grid of the parallel tester, and on which contact pins are arranged along one side edge. The contact pins lie with their peripheral surfaces on flat sides of the circuit boards and protrude a short distance beyond the side edge of the circuit board. They are connected electrically and physically to contact fields formed on the circuit board. This arrangement of the contact pins is cost-effective to produce, mechanically stable, and permits the production of modules with a high density of contact pins.
