ABSTRACT:
A finger tester for testing non-componented printed circuit boards uses two or more test fingers, each having a test probe. A detection device is provided above each test probe for optical detection of the position above the circuit board of at least one contact tip of the test probe. The detection devices of the test fingers are each arranged in different vertically spaced planes, so that areas of the detection devices located above the test fingers are positioned above one another, aligned vertically to prevent contact during testing.
