Abstract
Abstract A method of soldering an integrated circuit with yielding connecting contacts rigidly mounted on the integrated circuits to printed circuit boards. The integrated circuit is inserted in a clamped manner into a formed opening in a printed circuit board and the connecting contacts are soldered with the conductors by means of customary soldering methods for mass production such as by wave soldering.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A method of incorporating an integrated circuit into a printed circuit board having conductors thereon, wherein said integrated circuit includes a housing having a plurality of yieldable contacts rigidly mounted on its perimeter, said method comprising: (a) providing said integrated circuit; (b) providing a printed circuit board; (c) providing an opening in the printed circuit board slightly smaller than the outer dimensions of the housing and contacts of the integrated circuit; (d) placing the integrated circuit in the opening of the printed circuit board such that the contacts are biased against or clampingly engage the sides of the opening so as to maintain the integrated circuit in position therein; and (e) soldering the contacts with respective conductors on the printed circuit board.
Claim 2
Independent Claim
122 words
A method of incorporating an integrated circuit into a printed circuit board having conductors thereon, wherein said integrated circuit includes a housing having a plurality of yieldable contacts rigidly mounted on its perimeter, said method comprising: (a) providing said integrated circuit; (b) providing a printed circuit board; (c) providing an opening in the printed circuit board slightly smaller than the outer dimensions of the housing and contacts of the integrated circuit; (d) placing the integrated circuit in the opening of the printed circuit board such that the contacts are biased against or clampingly engage the sides of the opening so as to maintain the integrated circuit in position therein; and (e) soldering the contacts with respective conductors on the printed circuit board.
Claim 3
Dependent Claim
21 words
The method in accordance with claim 1 which includes the step of providing said opening by stamping said printed circuit board.
Claim 4
Dependent Claim
27 words
The method in accordance with claim 2 which includes the step of providing an opening which is rectangular in shape and an integrated circuit of similar shape.
Claim 5
Dependent Claim
38 words
The method in accordance with claim 3 which includes the step of pressing said integrated circuit into said opening such that it is relatively flush with the printed circuit board on the side at which soldering takes place.
Claim 6
Dependent Claim
20 words
The method in accordance with claim 4 which includes the step of soldering said contacts and conductors by wave soldering.
Claim 7
Dependent Claim
20 words
The method in accordance with claim 1 which includes the step of soldering said contacts and conductors by wave soldering.
