Abstract
Abstract A socket adapted to receive an integrated circuit having a body with outer opposed walls, having upper edges and a plurality of substantially flat contacts biased to a closed position within the socket body. The leads of the integrated circuit to be tested engage the contacts. The contacts extend over the upper edge of the walls and are then turned downwardly to form a neck portion of reduced width compared to the width of the contact disposed within the socket 40.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
In a burn-in tray having a plurality of dip burn-in sockets arrayed thereon, the sockets having ribbon-like contacts in side-by-side relationship received therein and extending externally of the socket body, resistors secured to the contacts external of said sockets, the improvement which comprises: The contacts having a first larger width within the socket body, the contacts extending externally of the socket body formed into a necked portion of a second width narrower than the first width, the contact terminating in a depending end of a third width narrower than the first width which end is adapted to receive the lead of a resistor; and wherein the socket body includes outer walls each having upper edges, the necked portion extends across the upper edge and then downwardly.
Claim 2
Dependent Claim
