A module for a tester for the testing of circuit boards is described. Such testers have a basic grid on which an adapter and/or a translator may be arranged in order to connect contact points of the basic grid with circuit board test points of a circuit board to be tested. The module comprises a support plate and a contact board. The contact board is formed by a rigid circuit board section which is described as the basic grid element, and at least one flexible circuit board section. Provided on the basic grid element are contact points which each form part of the contact points of the basic grid. The basic grid element is mounted at an end face of the support plate, and the flexible circuit board section is bent in such a way that at least part of the other section of the contact board is parallel to the support plate. Each of the contact points of the basic grid element is in electrical contact with conductor paths running in the contact board and extending from the basic grid element into the flexible circuit board section.

Module for test device for testing circuit boards

A method and a device for loading an adapter for a printed circuit board testing device with adapter pins having head ends and contact ends. The adapter pins to be loaded into the adapter are transferred by gravity from at least one main magazine, with their head ends first, into an intermediate magazine. Also, the adapter pins that have been transferred into the intermediate magazine are then transferred by gravity with the contact ends first into the adapter. For simpler and more rapid loading of the adapter with minimal constructional outlay, the adapter pins are transferred from the main magazine head first into the intermediate magazine.

Method for loading an adapter for a device for testing printed circuit

An adapter (13) for a printed circuit board testing device (6), by means of which test contacts, (7) which are located in a grid, may be connected with test points (3), which are located in and/or beyond the grid, on a printed circuit board (2), which is to be tested, the connection being effected by means of adapter pins (14) which extend through first, second and third guide plates (10, 15 and 16), the third guide plate (16) being arranged between the first and second guide plates (10 and 15). The third guide plate (16) is arranged to be shifted square to the first and second guide plates (10 and 15) and guide holes (20) in the third guide plate (16) are provided at all points of the grid. The holes (20) have a diameter which tolerates a limited amount of clearance for steering of the adapter pins (14) in these guide holes (20).
