Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
196 words
A method for testing and/or providing chip burn-in signals and power to an array of regularly spaced individual raised electrical contacts on the surface of a substrate comprising the steps of: providing a mounting fixture having a plurality of pins carried thereby, providing at least one of said pins with a plurality of circumferentially spaced conducting members electrically insulated from each other, said at least one pin being configured and mounted on said fixture to move into and out of engagement with portions of at least two of said electrical contacts upon movement of the fixture and substrate with respect to each other, moving said fixture and said substrate with respect to each other to bring said pins into engagement with said at least two electrical contacts, performing a test and/or burn-in function by providing electrical signals from each of said conducting members on each of said pins to said electrical contacts independently to perform test or burn-in functions independently through each of said contacts and independent of any other conducting member, and thereafter moving said fixture and said substrate with respect to each other to move said pins out of impact with said electrical contacts.
Claim 2
Independent Claim
196 words
A method for testing and/or providing chip burn-in signals and power to an array of regularly spaced individual raised electrical contacts on the surface of a substrate comprising the steps of: providing a mounting fixture having a plurality of pins carried thereby, providing at least one of said pins with a plurality of circumferentially spaced conducting members electrically insulated from each other, said at least one pin being configured and mounted on said fixture to move into and out of engagement with portions of at least two of said electrical contacts upon movement of the fixture and substrate with respect to each other, moving said fixture and said substrate with respect to each other to bring said pins into engagement with said at least two electrical contacts, performing a test and/or burn-in function by providing electrical signals from each of said conducting members on each of said pins to said electrical contacts independently to perform test or burn-in functions independently through each of said contacts and independent of any other conducting member, and thereafter moving said fixture and said substrate with respect to each other to move said pins out of impact with said electrical contacts.
Claim 3
Dependent Claim
33 words
The invention as described in claim 1 further characterized by: providing some of said pins with four electrical members which are configured and mounted to engage at least four of said electrical contacts.
Claim 4
Dependent Claim
36 words
The invention as described in claim 1 further characterized by providing openings in said fixture with said pins being slidably mounted in said openings and having biasing devices engaging said pins urging them toward said substrate.
Claim 5
Dependent Claim
20 words
The invention as described in claim 2 wherein the contacts and the pins are both arranged in a rectilinear pattern.
Claim 6
Dependent Claim
29 words
The invention as described in claim 4 wherein the spacing of the centers of the pins is about twice that of the spacings of the centers of the contacts.
Claim 7
Dependent Claim
24 words
The invention as defined in claim 1 further characterized by providing mounting of said pins for movement to align the pins with said contacts.
Claim 8
Dependent Claim
28 words
The invention as defined in claim 3, wherein said openings are larger than the pins to provide self alignment of the pins with the contacts on the substrate.
Claim 9
Dependent Claim
29 words
The method of claim 1 further characterized by providing a plurality of said pins with said circumferentially spaced conducting members, and arranged to contact a plurality of different contacts.
