SMT patch components are very small and light, and patch components are easier to weld than lead components. Another important advantage of SMD is that it improves the stability and reliability of the circuit. For production, it improves the success rate of production. What about the welding method of SMT chip processing factory components and lead components? SMT patch components are very small and light, and patch components are easier to weld than lead components. Another important advantage of SMD components is that it improves the stability and reliability of the circuit, thus improving the success rate of production. This is because the patch element has no lead, which reduces the stray electric field and stray magnetic field, which is very obvious in high-frequency analog circuits and high-speed digital circuits.

Welding method of SMT patch element: put the element on the pad, then apply the adjusted solder paste on the element pin and pad (not too much to prevent short circuit), and then use 20W internal heating iron to heat the joint between pads and SMT patch assembly (temperature should be 220~230 ° C). After the solder is melted, the soldering iron can be removed. After the solder is solidified, the welding is completed. After welding, you can clamp the clamp assembly with tweezers to see if it is loose. If there is no looseness (it should be very strong), it means that the welding is good. If loose, reapply the paste and re-weld as described above. SMT lead element welding method: when welding all leads, solder should be coated on the soldering iron head, and all leads should be coated with flux to keep the pins wet. Touch the end of each pin of the patch with the soldering iron tip until you can see the solder flowing into the pin. During welding, keep the soldering iron head parallel to the welding lead to prevent overlap due to excessive welding. After welding all leads, wet all pins with flux to clean solder. Remove excess solder where necessary to eliminate any short circuits and turns. If you want to know more about SMT patch processing or need patch processing, you can find Changkeshun Technology.
