Leadless ceramic chip carrier printed wiring board adapter

Claim 2

A leadless ceramic chip carrier (LCCC) and a planar printed wiring board (PWB) assembly comprising: an LCCC having a plurality of terminals positioned in a first array; a PWB having a plurality of first conductors on a surface thereof each conductor corresponding to a terminal, said conductors terminating in a second array on said PWB surface; a pliable electrically non-conductive membrane having first and second surface and including a plurality of second conductors on said first surface, said second conductors terminating in said first array in one region of the membrane and in said second array in a second region of the membrane, said second region being adjacent to a peripheral edge of the membrane, the first conductors having corresponding second conductors, said membrane second surface and said PWB surface facing one another in juxtaposed relation; a plurality of first solder connections over said membrane peripheral edge connecting said first conductors to said second conductors at said terminating second array; and a plurality of second solder connections connecting said terminals to said second conductors at said terminating first array.

Claim 3

The assembly of claim 1 wherein said assembly further includes an adhesive for bonding said membrane second surface to said PWB surface adjacent to said first solder connections.

Claim 4

The assembly of claim 1 wherein said membrane comprises polyimide sheet material.

Claim 5

A leadless ceramic chip (LCCC) and printed wiring board (PWB) assembly comprising: a ceramic leadless LCCC having at least one peripheral edge defining an enclose geometric figure, said LCCC including a plurality of electrical terminals spaced along said at least one edge; a resinous PWB including a plurality of conductors on one surface thereof in a given orientation and spacing, each terminal corresponding to and for connection to at least one different PWB conductor; a polymide pliable member having first and second broad surfaces including an array of conductors on one of said surfaces, said member conductors being spaced, oriented and arranged in registration with said LCCC terminals, that member conductor in registration with a green terminal being aligned with said corresponding PWB conductor at an edge of the member, the other of said fist and second surfaces and said PWB one surface facing one another in juxtaposed relation; a first plurality of solde joints electrically conductively coupling said registered LCCC terminals and different member conductors and a second plurality of solder joints electrically conductively coupling each said aligned member conductor with its corresponding PWB conductor, said second plurality of solder joints extending over said edge of said member; and means for adheringly securing said member other surface to said PWB one surface at a local region of the member adjacent to said second plurality of solder joints.

Claim 6

A leadless ceramic chip (LCCC) and printed wiring board (PWB) assembly comprising: a ceramic leadless LCCC having at least one peripheral edge defining an enclose geometric figure, said LCCC including a plurality of electrical terminals spaced along said at least one edge; a resinous PWB including a plurality of conductors on one surface thereof in a given orientation and spacing, each terminal corresponding to and for connection to at least one different PWB conductor; a polymide pliable member having first and second broad surfaces including an array of conductors on one of said surfaces, said member conductors being spaced, oriented and arranged in registration with said LCCC terminals, that member conductor in registration with a green terminal being aligned with said corresponding PWB conductor at an edge of the member, the other of said fist and second surfaces and said PWB one surface facing one another in juxtaposed relation; a first plurality of solde joints electrically conductively coupling said registered LCCC terminals and different member conductors and a second plurality of solder joints electrically conductively coupling each said aligned member conductor with its corresponding PWB conductor, said second plurality of solder joints extending over said edge of said member; and means for adheringly securing said member other surface to said PWB one surface at a local region of the member adjacent to said second plurality of solder joints.
