Abstract
Abstract A clip-lead of unitary construction for use in making connections to thin film circuits and devices is described. The lead is of a flat design which makes it amenable to all types of external connecting means. The clip has a pincerlike head comprising a lower contacting member and multifurcated upper contacting members bonded to the mating bonding surface of the substrate.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
248 words
A device adapted to form a bonded electrical connection to a conductive pattern on a circuit board comprising a generally Ushaped flat metal spring clamp having a point of minimum spacing between the two legs of the U, said point being located at a position between the ends of each leg, said minimum spacing being less than the thickness of the circuit board to which the connector is to be bonded, so as to enable the connector to be clamped by its spring action to the board before and during the bonding of a first one of its legs to the conductive pattern on the circuit board, said legs being spaced apart from one another at their outer ends of distance greater than said minimum spacing so that when clamped upon a circuit board the said first leg tends to lie with a portion of its flat surface in contact with said conductive pattern, said first leg being slotted at and near its outer end so as to define a plurality of fingers each adapted to made contact with said conductive pattern, the second leg of the u being split into three longitudinal sections constituted by two outer sections and one middle section, the two outer sections remaining in the generally U-shaped configuration and being adapted, together wit said first leg, to exert a clamping action on the circuit board, the middle section being positioned outwardly from the U so as to serve as an integral electrical lead.
Claim 2
Independent Claim

Claim 3
Dependent Claim
23 words
Device in accordance with claim 1 wherein said middle section is positioned so as to constitute essentially a continuation of said first leg.
