Abstract

With the advance of printed-circuit board technology, especially in situations where there are no protrusions from the plane of the board, it is becoming increasingly difficult for field engineers, in testing apparatus in the field, to locate, probe and hold in place a plurality of probes at fixed points on the back of a printed-circuit board. This is especially difficult when there is a significant number of overflow wires on the side of the board to be probed.

Probe Guidance Template and Probe

With the advance of printed-circuit board technology, especially in situations where there are no protrusions from the plane of the board, it is becoming increasingly difficult for field engineers, in testing apparatus in the field, to locate, probe and hold in place a plurality of probes at fixed points on the back of a printed-circuit board. This is especially difficult when there is a significant number of overflow wires on the side of the board to be probed.

This problem is overcome by the use of a template which is adapted to be placed over the side of the board to be tested. The template is made of a flame- retardant material, and is easily attached to the frame or other apparatus that encompasses each board site. The template is exactly located at each board site by means of a plurality of locating points, which position each hole in the template with a respective board probing site. As suggested, the template contains a probing site for each point on the board to be tested.

In order to assure that the probes can be inserted into the respective test positions and still free the field engineer to perform readings, tests, etc., the probes are spring-loaded, and the holes in the template are tapered to provide a locking fit for the probe, thereby assuring a fixed contact to the test point.

To facilitate identification of the probe sites on the printed-circuit board, the template will include a plurality of positions for the p...
