Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A connector assembly for connecting a semiconductor electronics card with a device under test interface board, comprising; a mounting card for mounting at least one connector; an elastomer connector having electrical circuit paths thereon for connecting said electronics card with said device under test mounted on said mounting card; an elastomer support part for holding the elastomer connector in a fixed position on said monting card; and a retainer part having a metalized surface thereon mounted between the elastomer connector and mounting card for providing support for the elastomer connector.
Claim 2
Dependent Claim
90 words
A connector assembly for connecting a semiconductor electronics card with a device under test interface board, comprising; a mounting card for mounting at least one connector; an elastomer connector having electrical circuit paths thereon for connecting said electronics card with said device under test mounted on said mounting card; an elastomer support part for holding the elastomer connector in a fixed position on said monting card; and a retainer part having a metalized surface thereon mounted between the elastomer connector and mounting card for providing support for the elastomer connector.
Claim 3
Dependent Claim
28 words
The connector assembly according to claim 1, wherein the metalized surface on the retainer part in combination with the elastomer connector provides an adjustable impedance for the connector.
Claim 4
Dependent Claim
32 words
The connector assembly according to claim 1, wherein the mounting card has a circular configuration and has a plurality of slots for mounting elastomer connectors, said slots arrayed radially around the card.
Claim 5
Dependent Claim
99 words
A connector assembly for connecting a semiconductor electronics card with a device under test interface board, comprising; a mounting card for monting at least one connector; an elastomer connector having a plurality of electrical circuit paths thereon for connecting said electronics card with said device under test; an elastomer support part for holding the elastomer connector in a fixed position on said mounting card; and a retainer part mounted between the elastomer connector and mounting card such that the impedance of the connector may be varied by varying the spacing between the retainer and the conductors on the connector.
Claim 6
Dependent Claim
99 words
A connector assembly for connecting a semiconductor electronics card with a device under test interface board, comprising; a mounting card for monting at least one connector; an elastomer connector having a plurality of electrical circuit paths thereon for connecting said electronics card with said device under test; an elastomer support part for holding the elastomer connector in a fixed position on said mounting card; and a retainer part mounted between the elastomer connector and mounting card such that the impedance of the connector may be varied by varying the spacing between the retainer and the conductors on the connector.
Claim 7
Dependent Claim
15 words
The connector assembly according to claim 4, wherein the retainer part has a metalized surface.
Claim 8
Dependent Claim
32 words
The connector assembly according to claim 4, wherein the mounting card has a circular configuration and has a plurality of slots for mounting elastomer connectors, said slots arrayed radially around the card.
Claim 9
Dependent Claim
28 words
The connector assembly according to claim 4, wherein the elastomer connector is mounted such that contact is made to the connector on two sides of the mounting card.
