Abstract
Abstract An electronic module which comprises a printed circuit board, on which is mounted an MOS integrated circuit module, utilizes a resilient, stainless steel clip secured to the edge of the board to short out the conductive circuit runs to the integrated circuit module and to mask them from the solder bath in a wave soldering machine through which the printed circuit board is passed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
An electronic module comprising a printed circuit board carrying electronic components and an integrated circuit package secured to conductive runs on said board, said circuit package being sensitive to static electricity, and a protective clip coupled to said printed circuit board and covering and electrically shorting said conductive runs to said circuit package, said clip comprising a first large-area, flat plate and a second plate resiliently coupled thereto with a spring-like action, said second plate including at least two contact surfaces positioned adjacent to said first large-area plate for making two lines of contact with said printed circuit board inserted between said first and second plates whereby said clip intimately engages said board and said first large-area plate intimately contacts all of said conductive runs.
Claim 2
Dependent Claim
125 words
An electronic module comprising a printed circuit board carrying electronic components and an integrated circuit package secured to conductive runs on said board, said circuit package being sensitive to static electricity, and a protective clip coupled to said printed circuit board and covering and electrically shorting said conductive runs to said circuit package, said clip comprising a first large-area, flat plate and a second plate resiliently coupled thereto with a spring-like action, said second plate including at least two contact surfaces positioned adjacent to said first large-area plate for making two lines of contact with said printed circuit board inserted between said first and second plates whereby said clip intimately engages said board and said first large-area plate intimately contacts all of said conductive runs.
Claim 3
Dependent Claim
28 words
The module defined in claim 1 wherein said clip is made of a material to which solder does not adhere and which does not melt at soldering temperatures.
Claim 4
Dependent Claim
14 words
The module defined in claim 2 wherein said clip is made of stainless steel.
Claim 5
Dependent Claim
148 words
An electronic module comprising a printed circuit board carrying electronic components and an integrated circuit package secured to conductive runs on said board, said circuit package being sensitive to static electricity, and a protective clip coupled to said printed circuit board and covering and electrically shorting said conductive runs to said circuit package, said clip comprising a first large-area, flat plate and a second plate resiliently coupled thereto with a spring-like action, said second plate including a U-shaped portion including two walls and a connecting wall, said two walls having curved ends which face and are spaced adjacent to said large-area plate, said connecting wall being positioned remote from said curved ends of said two walls and said first plate, said curved ends of said two walls comprising contact surfaces which provide two lines of contact with said printed circuit board inserted between said first and second plates.
Claim 6
Dependent Claim
148 words
An electronic module comprising a printed circuit board carrying electronic components and an integrated circuit package secured to conductive runs on said board, said circuit package being sensitive to static electricity, and a protective clip coupled to said printed circuit board and covering and electrically shorting said conductive runs to said circuit package, said clip comprising a first large-area, flat plate and a second plate resiliently coupled thereto with a spring-like action, said second plate including a U-shaped portion including two walls and a connecting wall, said two walls having curved ends which face and are spaced adjacent to said large-area plate, said connecting wall being positioned remote from said curved ends of said two walls and said first plate, said curved ends of said two walls comprising contact surfaces which provide two lines of contact with said printed circuit board inserted between said first and second plates.
Claim 7
Dependent Claim
184 words
An electronic module comprising a printed circuit board carrying electronic components and an integrated circuit package secured to conductive runs on said board, said circuit package being sensitive to static electricity, and a protective clip coupled to said printed circuit board and covering and electrically shorting said conductive runs to said circuit package, said clip comprising a first large-area, flat plate, a second plate resiliently coupled thereto With a spring-like action, a first generally U-shaped portion interconnecting said first plate and said second plate, said second plate including a second generally U-shaped portion which includes first and second walls and a connecting wall, said first wall having a first curved end which extends into a wall of said first U-shaped portion, said second wall having a second curved end, said first curved end of said first wall and said second curved end of said second wall lying in substantially the same plane and comprising two contact surfaces positioned adjacent to said first large-area plate and adapted to provide two lines of contact with said printed circuit board inserted between said first and second plates.
Claim 8
Dependent Claim
184 words
An electronic module comprising a printed circuit board carrying electronic components and an integrated circuit package secured to conductive runs on said board, said circuit package being sensitive to static electricity, and a protective clip coupled to said printed circuit board and covering and electrically shorting said conductive runs to said circuit package, said clip comprising a first large-area, flat plate, a second plate resiliently coupled thereto With a spring-like action, a first generally U-shaped portion interconnecting said first plate and said second plate, said second plate including a second generally U-shaped portion which includes first and second walls and a connecting wall, said first wall having a first curved end which extends into a wall of said first U-shaped portion, said second wall having a second curved end, said first curved end of said first wall and said second curved end of said second wall lying in substantially the same plane and comprising two contact surfaces positioned adjacent to said first large-area plate and adapted to provide two lines of contact with said printed circuit board inserted between said first and second plates.
