ABSTRACT:
An apparatus for testing printed circuit boards.
In an apparatus for testing test points of a printed circuit board arranged on and/or off grid by means of an adapter which, during the testing, is arranged between contact elements of an electronic testing apparatus and a printed circuit board at a testing position, having a table shaped receiving device for the printed circuit boards with a frame arranged above it for holding the adapter and the testing apparatus, and having a centering device for the printed circuit boards, the delivery of the printed circuit boards is improved while ensuring convenience of operation. This is achieved by providing a movable carrier plate for receiving the printed circuit boards on which the printed circuit board can be centered by means of a first centering device and which can be conveyed in or to a pre-positioned position by means of a conveyor having at least one movable conveying element from an insertion position to the testing position, and by providing a second centering device for the carrier plate near the testing position.
