Abstract
Abstract A method and apparatus for testing and/or burning-in electronic devices such as capacitors is disclosed. The devices are loaded in a matrix having a multiplicity of apertures. A second matrix having complemental apertures is provided, the apertures of the second matrix being filled with fuses. The matrices are pressed together by yieldable electrodes which are connected with a source of current.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
202 words
The method of simultaneously processing electronic devices such as capacitors which comprises the steps of providing first and second stretchable elastomeric insulating matrices each having a multiplicity of throughgoing apertures formed therein, introducing said electronic devices into said apertures of said first matrix in such manner that said devices are frictionally supported in said apertures and opposed terminals of said devices are exposed at opposite surfaces of said matrix, introducing replaceable fuse members into the apertures of said second matrix in such manner that said fuse members are frictionally supported in said apertures and opposite terminals of said fuse members are exposed at opposite surfaces of said second matrix, superposing said first and second matrices in such manner that each terminal of a fuse in said second matrix engages against a respective terminal of a device in said first matrix, interposing said superposed matrices between first and second yieldable electrodes, one said electrode being in conductive contact with a terminal of each of said devices and the other of said electrode being in conductive contact with a terminal of each of said fuses, and thereafter subjecting said devices to testing conditions while simultaneously causing a voltage to be applied across said electrodes.
Claim 2
Independent Claim
202 words
The method of simultaneously processing electronic devices such as capacitors which comprises the steps of providing first and second stretchable elastomeric insulating matrices each having a multiplicity of throughgoing apertures formed therein, introducing said electronic devices into said apertures of said first matrix in such manner that said devices are frictionally supported in said apertures and opposed terminals of said devices are exposed at opposite surfaces of said matrix, introducing replaceable fuse members into the apertures of said second matrix in such manner that said fuse members are frictionally supported in said apertures and opposite terminals of said fuse members are exposed at opposite surfaces of said second matrix, superposing said first and second matrices in such manner that each terminal of a fuse in said second matrix engages against a respective terminal of a device in said first matrix, interposing said superposed matrices between first and second yieldable electrodes, one said electrode being in conductive contact with a terminal of each of said devices and the other of said electrode being in conductive contact with a terminal of each of said fuses, and thereafter subjecting said devices to testing conditions while simultaneously causing a voltage to be applied across said electrodes.
Claim 3
Dependent Claim
17 words
The method of claim 1 and including the step of sandwiching said electrodes between rigid backing plates.
Claim 4
Dependent Claim
23 words
The method in accordance with claim 2 and including the step of heating said devices while said voltage is applied to said electrodes.
Claim 5
Dependent Claim
63 words
The method in accordance with claim 1 and including the steps of testing said fuse carrying matrix to establish which of said fuses has been opened in the course of said testing procedure, and segregating the devices in said device carrying matrix which are positioned complementally in said device carrying matrix to the positions of the opened fuses in said fuse carrying matrix.
Claim 6
Dependent Claim
200 words
Apparatus for stress testing of capacitors having end terminations comprising first and second generally planar stretchable elastomeric matrices, said matrices each being provided with a multiplicity of through-going apertures, the apertures of one said matrix being aligned with the apertures of the other said matrix, the apertures of said first matrix each being sized to accommodate and removeably frictionally retain a capacitor while exposing the said end terminations of said capacitors at opposite sides of said matrix, the apertures of said second matrix being each sized to accommodate and removeably frictionally retain a fuse therein with distal portions of said fuses exposed at opposite sides of said matrix, first and second generally planar electrode means superposed over said first and second matrices respectively in overlying relation of said apertures, electrical current means connected to said electrode means for developing a voltage across said electrode means, and means for urging said electrode means toward each other to thereby press a distal end of the fuses in one said matrix against a termination of the capacitors in the other said matrix and simultaneously press the noninterengaged ends of said fuses and terminations into electrical contact with a respective one of aid electrodes.
Claim 7
Dependent Claim
200 words
Apparatus for stress testing of capacitors having end terminations comprising first and second generally planar stretchable elastomeric matrices, said matrices each being provided with a multiplicity of through-going apertures, the apertures of one said matrix being aligned with the apertures of the other said matrix, the apertures of said first matrix each being sized to accommodate and removeably frictionally retain a capacitor while exposing the said end terminations of said capacitors at opposite sides of said matrix, the apertures of said second matrix being each sized to accommodate and removeably frictionally retain a fuse therein with distal portions of said fuses exposed at opposite sides of said matrix, first and second generally planar electrode means superposed over said first and second matrices respectively in overlying relation of said apertures, electrical current means connected to said electrode means for developing a voltage across said electrode means, and means for urging said electrode means toward each other to thereby press a distal end of the fuses in one said matrix against a termination of the capacitors in the other said matrix and simultaneously press the noninterengaged ends of said fuses and terminations into electrical contact with a respective one of aid electrodes.
Claim 8
Dependent Claim
27 words
Apparatus in accordance with claim 5 wherein said means for urging said electrode means toward each other comprises a spaced pair of rigid planar compression plate members.
Claim 9
Dependent Claim
18 words
Apparatus in accordance with claim 5 and including means for heating said capacitors while yieldable pressure is exerted.
Claim 10
Dependent Claim
62 words
Apparatus in accordance with claim 5 in which said first and second generally planar matrices are of elastomeric material, each of the apertures of said first matrix being adapted to retain a capacitor therein by frictional engagement with a central portion thereof, and each of the apertures of said second matrix also being adapted to retain a fuse therein by frictional engagement.
Claim 11
Dependent Claim
19 words
Apparatus in accordance with claim 8 in which said first and second generally planar electrode means are resiliently deformable.
