Preparation of Metallic Materials for Electronic Packaging Based on Space Environment

With the rapid development of electronic manufacturing technology, the metallic materials used for electronic packaging products have strongly requirements of improved the performance and reliability. Space material science is an emerging field of space technology and material science. The space environment has the characteristics of containerless, microgravity and ultra high vacuum. The highly undercooled liquid metal can be rapidly solidified under space environment, which provides an effective way to prepare metallic materials with significantly refined microstructure and excellent physicochemical properties. The solidification of metal materials in the space environment has shown a wide application prospect in the field of electronic equipment manufacturing. This article starts with the electrostatic levitation technology, summarizes the recent research results of space materials science, and provides new ideas for the development and preparation of new metal materials for electronic packaging.
