Finger tester for testing of non-componented circuit boards and method for testing unequipped printed circuit boards with a finger tester

摘要

The present invention relates to a finger tester for testing of non-componented circuit boards with at least two test fingers (1), which in each case have a test probe (2), wherein above of each test probe (2), in each case, a detection device (20) to the optical detecting the position of at least one contact tip of the test probe (2) is present. The detection means (20) of the at least two test probes (1) are arranged in different vertically spaced planes, so that at least portions of the detection devices (20), the above the test fingers (2) are arranged, vertically aligned manner and can be positioned one above the other in a contactless manner.
