With the full penetration of 5G communication technology in the field of electronic technology and the promotion of market demand, the 3C product manufacturing industry will develop rapidly. Opportunities and challenges coexist, interests and risks coexist! Stimulate innovation and innovate the manufacturing industry to develop towards a more refined, faster and higher technical level.

Laser soldering technology brings more development space to the electronics industry

With the refined, thin, short, small and differentiated development of electronic components, the traditional process has become more and more unable to meet the needs of ultra-fine and miniaturized electronic substrates and multi-layer point parts welding. Laser soldering has gradually become a new technology to make up for the shortcomings of traditional welding processes with technical advantages such as "non-contact welding, no static electricity, and real-time quality control", and has been widely used in the industry.


A New Soldering and Mounting Process - Laser Solder Ball Welding

As a brand-new soldering and mounting process, the solder ball soldering process has great technical advantages for the soldering of components with small pads and dense spacing compared with the traditional soldering process. Solder ball welding is a new type of soldering technology that uses high energy density laser heating to melt solder balls to achieve circuit connection.
