The Solder Paste used in the SMT surface mount process is a welding material produced by Solder paste manufacturer. Due to the increasing use of SMT mounting, New materials for electric welding came into being. Solder paste pilling is caused by errors in the printing operation. JJY Solder Paste Manufacturer now informs our partners of the main factors involved:

In the printing process, the first issue is stirring when the temperature is too low. The second reason is that organic solvents are volatile and prone to evaporation. The third is that Solder paste dries on the stencil. The fourth is that when Reflow Soldering is used, the temperature rises rapidly, resulting in an overly fast boiling rate. The fifth point is that the environment is relatively humid and no drying treatment has been carried out. Sixth, the solder paste dries easily and the tin powder particles are too fine. The seventh point is that solder paste exposed to the air is prone to oxidation, and incorrect operation of the squeegee can cause solder balls.

Overall, SMT Solder Paste printing should be carried out by Solder Paste Manufacturers in accordance with the requirements and instructions to avoid accidents during operation. The printing of solder paste is very important. A good solder paste can save a lot of trouble.

For example, the solder paste from JJY Industrial Technology Co., LTD comes in various specifications and can be developed alongside 5G synchronous circuit boards, SMT surface mount technology, lead-free tin wire for mobile phones, and 5G wireless communication technology.

In the electronics industry, Shenzhen JJY Industrial Technology Co., LTD focuses on the combination of the soldering industry and the electronics industry. With 12 years of R&D and production experience, we produce solder paste, Solder Wire, Solder Bar, and Leaded Solder Paste. In terms of R&D, JJY is a reliable solder paste manufacturer.
