Abstract
Abstract Disclosed is a method of producing an integrated circuit package, wherein portions of The package are electroplated by getting a direct electrical connection with each of lead pins joined to a package substrate. The electrical connection is obtained by force-fitting each of the lead pins in corresponding one of openings formed in a plating jig made of an electrically conductive material for thereby bringing a side surface of each of the lead pins in contact with the jig. The portions of the package are electroplated under the condition where each of the lead pins is held in conduction. After the electroplating, each of the lead pins is separated from the jig through movement in the direction differing from an axial direction of each of the lead pins. Various jigs used for carrying out the above method are also disclosed.

Claim 1
Independent Claim
113 words
A method of producing an integrated circuit package, wherein portions of the package are electroplated by getting a direct electrical connection with each of lead pins joined to a package substrate, characterized in that said direct electrical connection is obtained by bringing a side surface of each of said lead pins in contact with a plating jig made of an electrically conductive material, said portions of said package are electroplated under the condition where each of said lead pins is held in conduction, and thereafter each of said lead pins is separated from said plating jig through movement in a the direction diverging from an axial direction of each of said lead pins.
Claim 2
Independent Claim
113 words
A method of producing an integrated circuit package, wherein portions of the package are electroplated by getting a direct electrical connection with each of lead pins joined to a package substrate, characterized in that said direct electrical connection is obtained by bringing a side surface of each of said lead pins in contact with a plating jig made of an electrically conductive material, said portions of said package are electroplated under the condition where each of said lead pins is held in conduction, and thereafter each of said lead pins is separated from said plating jig through movement in a the direction diverging from an axial direction of each of said lead pins.
