With the advent of the post-Moore era, electronic components are gradually developing in the direction of miniaturization, complex structure, and functional integration. Laser soldering has become popular for improving soldering processes with its unique advantages of non-contact, selective local heating, and high precision. What we know is that laser soldering can solve the problems of difficulty in improving precision and the high cost of small batch production in traditional reflow soldering. Since intermetallic compounds play a vital role in the reliability of solder joints, researchers are eager to discover the impact of laser soldering on the evolution of intermetallic compounds in solder joints.
