Abstract
Abstract A method for the construction of a high density electrical connector for connecting a printed circuit board with a burn-in board in a burn-in system. The method comprises the steps of attaching a standard edge connector to a printed circuit board to form a first set of contacts, attaching two outer contact strips to the printed circuit board to form a second set of contacts, and enclosing the outer contact strips and the edge connector in an outer housing. The edge connector and the outer contact strips are secured to the printed circuit board through soldering. A burn-in board having a plurality of contact pads thereon can be inserted into the electrical connector such that the contact pads come into contact with the first and second set of contacts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
229 words
A method of manufacturing a high density electrical connector for electrically connecting a burn-in board having two rows of contact pads on each of a first side and a second side to a printed circuit board in a burn-in system, the method comprising the steps of: providing a standard edge connector having a connector housing made of a non-conductive material, the connector housing containing a first inner contact row and a second inner contact row, each inner contact row comprising a plurality of inner contacts; attaching the standard edge connector to a first side of the printed circuit board by inserting a first end of each inner contact into one of a plurality of apertures in the printed circuit board and soldering it in place; attaching a prefabricated first outer contact strip comprising a plurality of outer contacts to the printed circuit board by inserting a first end of each outer contact into one of the apertures and soldering it in place; attaching a prefabricated second outer contact strip comprising a plurality of outer contacts to the printed circuit board by inserting the first end of each outer contact into one of the apertures and soldering it in place; enclosing the first outer contact strip, the second outer contact strip and the standard edge connector within an outer housing; and securing the outer housing to the printed circuit board.
Claim 2
Independent Claim
229 words
A method of manufacturing a high density electrical connector for electrically connecting a burn-in board having two rows of contact pads on each of a first side and a second side to a printed circuit board in a burn-in system, the method comprising the steps of: providing a standard edge connector having a connector housing made of a non-conductive material, the connector housing containing a first inner contact row and a second inner contact row, each inner contact row comprising a plurality of inner contacts; attaching the standard edge connector to a first side of the printed circuit board by inserting a first end of each inner contact into one of a plurality of apertures in the printed circuit board and soldering it in place; attaching a prefabricated first outer contact strip comprising a plurality of outer contacts to the printed circuit board by inserting a first end of each outer contact into one of the apertures and soldering it in place; attaching a prefabricated second outer contact strip comprising a plurality of outer contacts to the printed circuit board by inserting the first end of each outer contact into one of the apertures and soldering it in place; enclosing the first outer contact strip, the second outer contact strip and the standard edge connector within an outer housing; and securing the outer housing to the printed circuit board.
Claim 3
Dependent Claim
14 words
The method of claim 1 wherein the printed circuit board comprises a driver/receiver board.
Claim 4
Dependent Claim
23 words
The method of claim 1 wherein the printed circuit board comprises an adapter board that can be electrically connected with a driver/receiver board.
Claim 5
Dependent Claim
25 words
