The key technology of electronic machine assembly and assembly - wave soldering has been extensively used in our country. In order to make the majority of workers in the assembly line to pay, technicians have a comprehensive understanding of the wave soldering process. By the Department of Radio Electronics Tsinghua University, Beijing Science and Education Film Studio film 35mm color science film “printed circuit board welding” has been completed by the Chinese film distribution company in the domestic public offering. The film starting from the principle of soldering, focusing on printed circuit board soldering wave soldering process technology, equipment and quality of solder joints made a comprehensive introduction. The audience for the movie is electricity
