inSMTIn the process of solder paste surface mount processing, many people are puzzled. Besides conducting tests to verify the solder paste, printing it on the circuit board, and verifying the quality of the soldering through reflow soldering after surface mount, what other methods can be used to verify the quality of the solder paste in advance?That is to say, before the pre-placement, the quality of the solder paste is tested through some standards. Because the quality of solder paste will directly affect the entire connectivity of electronic products after soldering, not only the structural connection but also the electrical performance......

Solder paste isSMTThe indispensable solder in the process is widely used in reflow soldering. It has a certain viscosity at room temperature and can initially bond electronic components to the predetermined position. At the welding temperature, as the solvent and some additives evaporate, the welded parts will connect with each other, forming a permanent connection. Now, let's have JJY solder Paste Manufacturer explain itPCBAHow to choose solder paste for processing? At present, solder paste coating is mostly adoptedSMTThe steel mesh printing method is characterized by simple operation, speed and accuracy.......
