Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A tool for a DIP-type IC comprising: an inverted U-shaped body having two elastic parallel arms respectively having two free ends and means for inserting said IC on a PCB and for removing said IC from said PCB, said means including a lip on each of said free ends for removing said IC and an end piece rotatably fastened to each arm, each end piece having a surface for inserting said IC and a recess for covering said lip during said inserting, whereby said end piece is rotated away from said lip during said removing and is rotated to cover said lip during said inserting.
Claim 2
Dependent Claim
105 words
A tool for a DIP-type IC comprising: an inverted U-shaped body having two elastic parallel arms respectively having two free ends and means for inserting said IC on a PCB and for removing said IC from said PCB, said means including a lip on each of said free ends for removing said IC and an end piece rotatably fastened to each arm, each end piece having a surface for inserting said IC and a recess for covering said lip during said inserting, whereby said end piece is rotated away from said lip during said removing and is rotated to cover said lip during said inserting.
Claim 3
Dependent Claim
16 words
A tool according to claim 1 wherein said U-shaped body is made of a spring steel.
Claim 4
Dependent Claim
25 words
A tool according to claim 1 wherein each said end piece is pivotable on a plane containing a side surface of one of said arms.
Claim 5
Dependent Claim
