Abstract: A testing system for automatic testing of circuit boards (1) in a circuit board manufacturing line. The testing system comprises a set (I) of test modules (4) comprising a testing apparatus. Each test module comprises a horizontal module conveyor (5) for conveying a circuit board (1) into and out of the test module. The test modules are arranged in a superposed relation with respect to each other. The set (I) contains test modules differing from each other so that the testing operations performed by these test modules are different from each other. A feed device (6) has been fitted to receive circuit boards from the first line conveyor (3) and to feed them into the test modules (4).

The system comprises a set of test modules (4) comprising a testing apparatus, each test module comprising a horizontal module conveyor (5) for moving a circuit board (1) into and out of the test module, which test modules are arranged into a superposed relation with respect to each other. A feed device (6) has been fitted to receive and arrange a number of circuit boards from a first line conveyor (3) into a superposed relation with respect to each other so that the circuit boards (1) lie at a distance from each other corresponding to the distance between the module conveyors (5) and to feed the circuit boards substantially simultaneously into the test modules (4).
