1、 Preface: The following is a solder paste composed of a solder lead ratio of 63/37, assembled on a FR-4 board with a foot spacing of 0.6mm or more. And it is a high-quality, small quantity, and high mixing SMT assembly process. The purpose of this article is to describe the three main steps in the SMT process: solder paste printing, component placement, and the first thing that needs to be done after reflow soldering. Visual inspection "can also be used as a way to determine the quality of the manufacturing process after the process step.
High temperature reflow soldering machine R6-400 degree high temperature soldering
In order to enable electronic devices to function properly in various harsh environments, there is an urgent need for an integrated circuit that can work properly in special environments such as high temperatures. Researchers at the University of Arkansas in the United States have designed an integrated circuit that can operate at temperatures above 350 ° C (approximately 660 ° F).
