Abstract

This is a probing device particularly adapted to probe electrical points on high-density printed circuit boards and cards, or the like, for high-performance technology. The probing device comprises a precision preperforated mask 1 in combination with a signal probe element 2 and a ground probe element 3. The mask 1 is arranged for mounting in a predetermined spaced relationship to a printed circuit board 4 undergoing a test routine. The mask 1 is provided with precisely located tapered holes. The ground probe element 3 fits into its respective tapered hole 5 in the mask. The contacting element 6 is slidably supported within the tip 3a of the ground probe element 3 and biased into contact with the ground conductor element 7 by means of the spring 8.

Taper Lock Probing Device

This is a probing device particularly adapted to probe electrical points on high-density printed circuit boards and cards, or the like, for high-performance technology. The probing device comprises a precision preperforated mask 1 in combination with a signal probe element 2 and a ground probe element 3. The mask 1 is arranged for mounting in a predetermined spaced relationship to a printed circuit board 4 undergoing a test routine. The mask 1 is provided with precisely located tapered holes. The ground probe element 3 fits into its respective tapered hole 5 in the mask. The contacting element 6 is slidably supported within the tip 3a of the ground probe element 3 and biased into contact with the ground conductor element 7 by means of the spring 8. The contacting element 6 is connected electrically with the ground conductor of the cable 9.

The signal probe element 2 is slidably positioned within its tapered hole 10 in the mask 1 with the contacting tip 2a adapted to make electrical contact with a circuit conductor of the printed circuit board 4. The contacting tip 2a is electrically connected by means of a wire 11 with the signal conductor of the cable 9. The cable 9 is suitably arranged for connection with appropriate test indicating equipment (not shown).
