TEST SYSTEM FOR EQUIPPED AND UNEQUIPPED PRINTED CIRCUIT BOARDS

摘要

A device for testing substantially flat circuit carriers or printed circuit boards which are unequipped or which are equipped with electronic components comprises a contact connection device having a plurality of test needles, each test needle being provided in accordance with the invention with its own motor drive for setting the position of the tip of the test needle at any points of a three-dimensional portion of space at the contact connection device ("dancing needles"). For this purpose each test needle is disposed in a currently preferred embodiment on its own platform which is in the form of a wobble plate and the position of which can be adjusted in space by motor.
