Printed circuit boards are tested in accordance with a method in which the circuit boards ( ) are brought into contact with conducting test-contact elements ( ) at certain contact points ( ) which are connected to the conductor tracks ( ), the test-contact elements ( ) or a partial number thereof are connected, in succession in clock-pulsed manner according to a certain test program, to a test-voltage source ( ) and during each test clock pulse the flowing via the test-contact elements ( ) or a parameter related thereto is measured. Particularly for circuit boards ( ) to be tested having a high contact-point density, the testing-time can be shortened by the circuit boards being subdivided into a plurality of test areas and all or at least some of the test areas being tested in parallel. The method is especially suitable for circuit boards that are produced in a multiple panel.
