Abstract
Abstract An adaptor for electrically connecting an irregular array of terminals of a circuit device to be tested to a regular array of terminals of a universal test fixture for automatic testing equipment. The adaptor includes a top plate having an aperture pattern that corresponds to the terminal pattern of the circuit device, a bottom plate having an aperture pattern that corresponds to the universal test fixture, and an alignment plate intermediate the top and bottom plates having apertures so disposed as to guide rigid probes extending from individual ones of the apertures in the top plate into preselected ones of the apertures in the bottom plate. A method for fabricating the adaptor is also disclosed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
215 words
A method for fabricating an adaptor for automatic testing equipment comprising the steps of: aligning a first plate having a plurality of apertures each having a first size and arrayed in a first pattern that conforms to the pattern of an electronic circuit device to be tested with a second plate having a plurality of apertures each having a second size larger than the first size and arrayed in a second pattern that corresponds to the pattern of the terminals of the electronic circuit device to be tested such that confronting ones of the apertures of the first and second plate are coaxially aligned; disposing a plurality of rigid probes each having tail portions through respective ones of said confronting aligned apertures in the first and second plates; displacing the second plate a selected distance in a selected direction in the plane defined by the plane of the second plate; positioning a third plate having apertures arrayed in a third pattern that conforms to the pattern of the signal contacts of a universal test fixture proximate the tails of the rigid probes; and vibrating the second plate controlably in the plane defined by the second plate such that corresponding ones of the tails are received in preselected ones of the apertures of the third plate.

A method for fabricating an adaptor for automatic testing equipment comprising the steps of: aligning a first plate having a plurality of apertures each having a first size and arrayed in a first pattern that conforms to the pattern of an electronic circuit device to be tested with a second plate having a plurality of apertures each having a second size larger than the first size and arrayed in a second pattern that corresponds to the pattern of the terminals of the electronic circuit device to be tested such that confronting ones of the apertures of the first and second plate are coaxially aligned; disposing a plurality of rigid probes each having tail portions through respective ones of said confronting aligned apertures in the first and second plates; displacing the second plate a selected distance in a selected direction in the plane defined by the plane of the second plate; positioning a third plate having apertures arrayed in a third pattern that conforms to the pattern of the signal contacts of a universal test fixture proximate the tails of the rigid probes; and vibrating the second plate controlably in the plane defined by the second plate such that corresponding ones of the tails are received in preselected ones of the apertures of the third plate.
Claim 3
Dependent Claim
27 words
The invention of claim 1, further including the step of displacing the second plate away from the first plate prior to said displacing in said plane step.
Claim 4
Dependent Claim
55 words
The invention of claim 1, wherein said disposing step includes the steps of positioning an egg-crate defining a plurality of chambers over said first plate; pouring a plurality of rigid probes into said chambers and controllably vibrating the first and second plates until said probes are slidably received in respective ones of said aligned apertures.
