Abstract:

A brazing process is provided that addresses the braze joint failure problems encountered in some multi-nozzle combustion end covers. The brazing process embodying the invention provides optimal, predictable low cycle fatigue joint life in particular when brazing 304L stainless steel parts using Amdry 915 braze alloy. The invention was realized in particular in the combination of and application of tightly controlled vital variables of gap, braze alloy, braze peak temperature hold time, cooling (quench) rate, surface finish and braze media to optimal limits for the process parameters. The process provides robust/reliable design limits for braze joints experiencing stress during operation.

Abstract:

An improved solder interconnection for forming I/O connections between an integrated semiconductor device and a support substrate having a plurality of solder connections arranged in an area array joining a set of I/O's on a flat surface of the semiconductor device to a corresponding set of solder wettable pads on a substrate, the improvement being a band of dielectric organic material disposed between and bonded to the device and substrate embedding at least an outer row of solder connections leaving the center inner solder connections and the adjacent top and bottom surfaces free of dielectric material.
