The present invention relates to a testing device and to a method for testing circuit boards, in particular un-equipped or partially-equipped circuit boards. The testing device is a flying probe with a shuttle or two sub-shuttles, which can displace a circuit board to be tested to a test area in an alternating manner. In addition, the sub-shuttles can be used for commonly holding a large circuit board.

Testing device and method for testing a printed circuit board

A cross-bar unit for a test apparatus for circuit boards having at least one cross-bar spanning a test field in which a circuit board to be tested may be placed, and is configured to hold positioning units for test fingers in a linearly traversable manner so that the test fingers are able to scan at least part of the test field. The cross-bar unit is configured to hold at least two linear guides, independent of one another, for guiding in each case at least one of the positioning units.
