1. A connector for facilitating the testing of integrated circuit packages comprising:
- (a) a retainer for connecting said connector to a testing rig, said retainer having a recess disposed lengthwise for facilitating connection with said test rig, and (b) a plurality of parallel conducting strips, each said conducting strip being embedded across said retainer such that one end protrudes as a leg across but within said recess, said leg adapted for electrical connection to said test rig, and the other end protrudes out as a finger from said retainer, each said finger further terminating at an angled finger tip, having a proximal portion proximal said retainer and a distal end portion extending therefrom, said distal portion further bent to form an angle such that the distal end points towards a first side, said tip further having a flat tongue portion with a planar surface and adapted for electrical contact with a lead of said integrated circuit package.

Abstract
A connector contact fingers of a testing rig which overcomes the co-planarity, contact and alignment difficulties in the testing procedure of integrated circuit packages. The connector comprises a tongue extension to the ends of the fingers to increase the surface area from which contact can be made with the device lead, a lever extension to the retainer along one side of the fingers to prevent deflection of the fingers, and a shoulder structure in the connector which acts as an adaptor to secure a flexible printed circuit board to the legs.

4. A connector for facilitating the testing of integrated circuit packages comprising:
-
(a) a retainer for connecting said connector to a testing rig, said retainer having a recess disposed lengthwise for facilitating connection with said test rig, (b) a plurality of parallel conducting strips, each said conducting strip being embedded across said retainer such that one end protrudes as a leg across but within said recess, said leg adapted for electrical connection to said test rig, and the other end protrudes out at a finger from said retainer, said finger adapted for electrical contact with a lead of said integrated circuit package; and
(c) a shoulder overhanging from each of the two ends of said recess of said retainer to define a slot, said slot indented within said shoulder wherein a card edge of a flexible printed circuit board may be inserted laterally within said slot and between said legs and said retainer, the height said slot being substantially the same as the thickness of the card end such that said card edge is prevented from causing deflection of said legs. - View Dependent Claims (5, 6)

7. A connector for facilitating the testing of integrated circuit packages comprising:
-
(a) a retainer for connecting said connector to a testing rig, said retainer having a recess disposed lengthwise for facilitating connection with said test rig, (b) a plurality of parallel conducting strips, each said conducting strip being embedded across said retainer such that one end protrudes as a leg across but within said recess, said leg adapted for electrical connection to said test rig, and the other end protrudes out as a finger from said retainer, each said finger having a proximal portion proximal said retainer and a distal portion extending therefrom, said distal portion further bent to form an angle such that the distal end points towards a first side, said tip of said finger further adapted for electrical contact with a lead of said integrated circuit package; and
(c) a substantially immovable lever projecting out from said retainer along the length of the fingers adjacent a second side opposite said first side, said lever positioned to stop said fingers from deflecting towards said second side when said tip of said finger come into contact with said leads of said integrated circuit package. - View Dependent Claims (8, 9)
