Description

technical field

[0001] The invention relates to the field of surface mount technology SMT, in particular to a printed circuit board solder paste printing machine for preventing solder paste oxidation. Background technique

[0002] With the development of science and technology, electronic products are more and more widely used in people's life. The large-scale production of electronic products drives the development of the circuit board production industry. Solder paste printing machines are used to print tin on the solder joints of circuit boards. The solder paste printing machine is an important executive mechanism in the SMT industry. It is responsible for accurately printing solder paste on the circuit board through the screen of the mold opening during the processing of the printed circuit board. In the printing process, the problems of lack of soldering and solder paste oxidation are prone to affect the quality of printed circuit boards.

[0003] In view of this, a ci...
