Abstract
Abstract A receptacle for installation on one surface of a circuit board for supporting a semiconductor package of the type having bonding pads along one side and providing an interconnection being the package and the circuit board. The receptacle has a generally channel-shaped planform with a series of contact members spaced apart along a central body section. The contact members extend upwardly and outwardly from one side and register with bonding pads of the package. The lower ends of the contact members extend through the circuit board for connection with lead terminals on its other surface.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
A receptacle adapted to be mounted on a circuit board for interconnecting it to a semiconductor package having a plurality of bonding pads spaced apart along one side, said receptacle comprising a central elongated body portion of non-conductive material; guide means extending from one side of said body portion; a series of metallic contact members spaced apart at predetermined intervals along the length of said body portion; said contact members each having an upper portion extending beyond one side of said body portion between said guide means and a lower portion fixed within and extending downwardly through said body portion, said lower portions of each pair of adjacent contact members in said body portion being formed to extend downwardly in opposite directions so that on the lower surface of said body portion the contact members are aligned in two spaced apart lines that extend longitudinally along said body portion.

Claim 3
Dependent Claim
159 words
In combination, a circuit board of uniform thickness having conductive leads on its lower surface, a receptacle fixed to said circuit board, said receptacle having a generally channel-shaped planform with a central body portion and arm portions forming guide means that extend from opposite ends thereof, a series of metallic contact members spaced apart at predetermined intervals along the length of said body portion, said contact members each having a curved upper portion that extends above the top surface and beyond one side of said body portion and a lower portion that is fixed within and extends downwardly through said body portion and through said circuit board, said lower portions of adjacent contact members being formed to extend from the lower surface of said receptacle body portion in two spaced apart lines that extend longitudinally thereon, and means for connecting the lower ends of said contact members to said conductive leads on the lower surface of said circuit board.
