Title: Innovations of Xin Qiao in Variable Melting Point Solders

Introduction

Xin Qiao is a notable inventor based in Boise, ID (US). She has made significant contributions to the field of materials science, particularly in the development of variable melting point solders and brazes. Her innovative approach has the potential to enhance the performance and reliability of soldering applications.

Latest Patents

Xin Qiao holds a patent for "Variable melting point solders and brazes." This invention involves compositions that comprise a metal or metal alloy powder with a low melting point combined with a metal powder that has a higher melting point. Upon heating, in-situ alloying occurs between the two powders, resulting in solidification at the solder or braze temperature. This process creates a new, higher solidus temperature with minimal intermetallic formation. For instance, a solder made from Sn powder mixed with a Sn–Bi eutectic powder has an initial melting point of 140°C and a re-melt temperature of 220°C after heating due to in-situ alloying.
