Abstract: The present invention relates to a method and apparatus for testing electrical traces wherein ultraviolet wavelengths from a laser source and visible wavelengths from a scanning camera are focused to a common focal plane. In a first embodiment of the method and apparatus, the wavelengths are commonly focused using an auxiliary lens having a power sufficient to accommodate the difference between the focusing plane of the ultraviolet laser source and the scanning camera. In a second embodiment, the wavelengths are commonly focused by moving the camera optics of the scanning camera relative to its visible light source. Both of these methods and apparatuses employ a fused silica lens system, avoiding the use of calcium fluoride.

Abstract: A tester for electrical traces such as on a circuit board generally comprises an electromagnetic beam source such as a laser producing an ultraviolet beam, a vacuum chamber, an electrode circuit including electrodes and corresponding electronics including ammeters for measuring photoelectron flow between traces and electrodes, a controller, laser beam optics, an image acquisition system, and a pair of broadband UV lights. The board containing traces under test is disposed in the vacuum chamber at lowered pressure with grid electrodes lying close to the trace area on each side of the board. Electrode electronics selectively maintain a known potential on each electrode. The exact location of traces are determined by an image acquisition system. The board and traces are initialized to a known voltage. Photoelectric effect using ultraviolet laser beams is used to determine continuity between two points on a trace and shorts between traces.

Abstract: A test interface between a two sided circuit board to be tested and a test controller and it generally includes an upper and a lower test fixture each including personality plates having bores for simultaneously guiding translation pins into contact with test nodes on the circuit board under test. Circuit board tooling bores are mounted on tooling pins in the personality plates. The tooling pins tapered to a diameter slightly larger than the diameter of the circuit board tooling bores. One or both personality plates are mounted such that they may move responsive to forces exerted on the tooling pins because of nonalignment such that the forces tend to equalize. This results in better overall alignment.
