Abstract
Abstract The present invention provides a method and an apparatus for manufacturing a pin grid array package assembly. According to this invention, the leads of the pin grid array package assembly are removably inserted into an electrically conductive plate containing detachable pin-clasp contacts. The plate clamps onto the ends of the leads, thereby forming a common electrical contact for the electroplating process. After the electroplating process has been completed and prior to shipping the package, the plate is detached without requiring the step of cutting ends of the leads from the plate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
96 words
A pin grid array package assembly comprising: a. a pin grid array package for housing an electronic device therein; b. a plurality of conductive leads, each lead having a first end disposed within the pin grid array package and a second end disposed outside of the pin grid array package; and c. an electrically conductive plate detachably mounted near the second ends of the leads wherein the plate further comprises a plurality of pin-clasp contacts, each for friction-fitting around the second end of a corresponding one of the leads, thereby providing electrical continuity to each lead.
Claim 2
Dependent Claim
96 words
A pin grid array package assembly comprising: a. a pin grid array package for housing an electronic device therein; b. a plurality of conductive leads, each lead having a first end disposed within the pin grid array package and a second end disposed outside of the pin grid array package; and c. an electrically conductive plate detachably mounted near the second ends of the leads wherein the plate further comprises a plurality of pin-clasp contacts, each for friction-fitting around the second end of a corresponding one of the leads, thereby providing electrical continuity to each lead.
Claim 3
Dependent Claim
53 words
A pin grid array package assembly according to claim 1, wherein the pin-clasp contact comprises a plurality of contact prongs formed in an approximately circular pattern, each prong facing in toward the center of the pattern into which the second end of the corresponding lead is inserted and engaged by the contact prongs.
Claim 4
Dependent Claim
45 words
A pin grid array package assembly according to claim 1, wherein the pin-clasp contact comprises a hole for receiving the second end of a corresponding lead and a single contact prong within the hole for engaging a portion of the lead near the second end.
Claim 5
Dependent Claim
19 words
A pin grid array package assembly according to claim 1, wherein the plate is formed by an etching process.
Claim 6
Independent Claim
72 words
An apparatus for maintaining substantially all of the pins of the packages for electronic devices at essentially the same electrical potential, the pins of the packages being, electrically-conductive and arranged to form a pin grid array; the apparatus comprising a detachable, electrically-conductive removable plate for detachable receiving the pins of the pin grid array, the plate including a plurality of pin-clasping contacts which each apply compressive force to a pin inserted therein.
Claim 7
Independent Claim
72 words
An apparatus for maintaining substantially all of the pins of the packages for electronic devices at essentially the same electrical potential, the pins of the packages being, electrically-conductive and arranged to form a pin grid array; the apparatus comprising a detachable, electrically-conductive removable plate for detachable receiving the pins of the pin grid array, the plate including a plurality of pin-clasping contacts which each apply compressive force to a pin inserted therein.
Claim 8
Dependent Claim
15 words
An apparatus according to claim 5, wherein the plate is formed by an etching process.
