In recent years, with increasingly fierce competition in the consumer electronics market, the electronics manufacturing industry has placed higher demands on its products. Traditional processing methods are prone to unstable product quality, component melting, difficulty in forming proper weld nuggets, and low yield rates. The emergence of laser processing technology can quickly solve these problems for electronics manufacturers. In the production of high-end electronic products, laser processing plays a significant role in optimizing product size and improving quality, making products lighter, thinner, and more robust. It is estimated that approximately 70% of the electronic product manufacturing process utilizes laser technology (more than 20 different processes) and related manufacturing equipment.

Currently, laser precision spot welding is mainly used for electronic product housings, shielding covers, USB connectors, conductive patches, etc., offering advantages such as minimal thermal deformation, precise control of the working area and position, high welding quality, the ability to weld dissimilar materials, and ease of automation. However, different welding methods are required when welding different materials.
