Abstract
Abstract A stud and support arrangement are provided for supporting and fixing electronic components on integrated circuit boards. Studs are provided having an abutment for accurately positioning the integrated circuit and facilitating soldering thereof. The stud has a semi-open structure for receiving the lug of an electric component. The lug is soldered to the stud. The electronic component may be easily separated from the integrated circuit because the semi-open structure enables each lug to be unsoldered and removed, one-by-one, thus alleviating the need to unsolder all lugs at one time.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A stud for fixing an electronic component to a printed circuit board, said stud comprising: a pin fixing said stud on a printed circuit board, said stud supporting an electronic component having lugs, said pin electrically connecting said lugs of said electronic component to said printed circuit board; and means receiving said lug, said receiving means including at least one abutment portion having an abutment face which by abutting said lug, positions said lug to said stud, the portion of said receiving means opposite said abutment portion being open to the extent that said lug has unhindered access to said abutment face and abuts said abutment portion on said abutment face, and said abutment portion being open to the extent that solder can be withdrawn.
Claim 2
Dependent Claim
125 words
A stud for fixing an electronic component to a printed circuit board, said stud comprising: a pin fixing said stud on a printed circuit board, said stud supporting an electronic component having lugs, said pin electrically connecting said lugs of said electronic component to said printed circuit board; and means receiving said lug, said receiving means including at least one abutment portion having an abutment face which by abutting said lug, positions said lug to said stud, the portion of said receiving means opposite said abutment portion being open to the extent that said lug has unhindered access to said abutment face and abuts said abutment portion on said abutment face, and said abutment portion being open to the extent that solder can be withdrawn.
Claim 3
Dependent Claim
13 words
A stud as claimed in claim 1, wherein said abutment face is concave.
Claim 4
Dependent Claim
24 words
A stud as claimed in claim 1, wherein said stud further includes a necked portion disposed between said lug receiving means and said pin.
Claim 5
Dependent Claim
30 words
A stud as claimed in claim 1, wherein said lug receiving means has an annular base and said abutment portion has a width greater than the radius of said base.
Claim 6
Dependent Claim
144 words
A support arrangement for an electronic component comprising: a plurality of support studs supporting an electronic component having a plurality of lugs, on a printed circuit board each of said studs including, a pin electrically connecting one of said lugs of said electronic component to said printed circuit board, means receiving one of said lugs, said receiving means including at least one abutment portion having an abutment face which by abutting said lug, positions said lug to said stud, the portion of said receiving means opposite said abutment portion being open to the extent that said lug has unhindered access to said abutment face and abuts said abutment portion on said abutment face and to the extent that solder can be withdrawn; and structural means supporting said support studs, with a portion of each of said support studs being fixed in said structural means.
Claim 7
Dependent Claim
144 words
A support arrangement for an electronic component comprising: a plurality of support studs supporting an electronic component having a plurality of lugs, on a printed circuit board each of said studs including, a pin electrically connecting one of said lugs of said electronic component to said printed circuit board, means receiving one of said lugs, said receiving means including at least one abutment portion having an abutment face which by abutting said lug, positions said lug to said stud, the portion of said receiving means opposite said abutment portion being open to the extent that said lug has unhindered access to said abutment face and abuts said abutment portion on said abutment face and to the extent that solder can be withdrawn; and structural means supporting said support studs, with a portion of each of said support studs being fixed in said structural means.
Claim 8
Dependent Claim
22 words
A support arrangement as claimed in claim 5, wherein said structural supporting means includes a wafer formed from a heat hardenable resin.
Claim 9
Dependent Claim
38 words
A support arrangement as claimed in claim 5, further including a plurality of bosses disposed between said structural supporting means and said structural printed circuit board forming a space between said supporting means and said printed circuit board.
Claim 10
Dependent Claim
110 words
A support arrangement as claimed in claim 5, wherein: said plurality of support studs, with a portion of each of said support studs, being fixed in said structural supporting means; said lugs are disposed on said electronic component and are resiliently bendable; and said disposition of said plurality of studs in said structural supporting means has spacing between said studs greater than the spacing of said lugs disposed on said electronic component so that when said electronic component is supported by said support arrangement, said lugs are resiliently bent to abut said stud abutment portion thus positioning said electronic component via said lugs to said support arrangement via said studs.
Claim 11
Dependent Claim
16 words
A support arrangement as claimed in claim 5, wherein said electronic component is an integrated circuit.
Claim 12
Dependent Claim
23 words
A support arrangement as claimed in claim 5, wherein said electronic component is an integrated circuit having dual, in line, rows of lugs.
