Abstract
Abstract An improved omega connector for electrically coupling components of a multicomponent electronic assembly comprises first and second flat end sections each formed of nonporous copper plate adapted for solder bonding to components, and an intermediate loop section formed of interwoven copper fibers extending between the end sections to provide a continous electrically conductive network therebetween. The fibers in the loop section carry a solder nonwettable coating to avoid interference with bonding operations to attach the end section to the components. Preferably, the loop section is composed of nickel-clad copper fibers. The fibrous loop section exhibits enhanced flexibility to reduce stresses attributed to shifting of the components during operation and thereby extend the useful life of the assembly.
