Abstract
An electrical interconnect including slotted lug with a receiving end for connecting to a flat electrical conductor and a fastening end for connecting to a surface mount terminal extending from the surface of a circuit, such as an integrated metal substrate (IMS) circuit board or a circuit card assembly. The interconnect provides a secure connection capable of transmitting a current of at least 100 Arms, to give a non-limiting example value. The interconnect further provides low contact resistance and ease of manufacturing.
