Claims
- 1. A tester for printed circuit boards comprising:
a fixture for mounting a printed circuit board; and a test head mounted above the fixture including a non-contact energy source for energizing a test circuit on the circuit board to test sites on the circuit board.
- 2. The tester of claim 1 further comprising a robot connected to a test head to move the test head in a three-dimensional plane.
- 3. The tester of claim 1 wherein the fixture is a translator fixture having a plurality of essentially parallel and vertically spaced apart translator plates having selected patterns of holes aligned in the translator plates for containing and supporting test probes for contacting a second surface of the circuit board.
- 4. The tester of claim 2 wherein the test head is mounted on a spindle of the robot and the energy source is a laser positioned on the spindle for directing a laser beam at the circuit board.
- 5. The tester of claim 2 wherein the test head is mounted on a spindle of the robot and the energy source is an electron gun positioned on the spindle for directing an electron beam at the circuit board.
- 6. A tester for printed circuit boards comprising:
a test fixture for mounting a printed circuit board to be tested; and a test head mounted above the fixture having non-contact means for energizing the circuit board to test sites on the circuit board; and a robot connected to the test head to move the test head in a three-dimensional plane.
- 7. The tester of claim 6 wherein the test fixture includes a plurality of essentially parallel and vertically spaced apart fixture plates having selected patterns of holes aligned in the fixture plates for containing and supporting test probes for contacting a second surface of the circuit board.
- 8. The tester of claim 6 wherein the non-contact means is a laser rigidly positioned at an end of the test head for directing a laser beam onto the circuit board.
- 9. The tester of claim 6 wherein the non-contact means is an electron gun positioned at an end of the test head for directing an electron beam onto the circuit board.
