Test soldering of the flux-cored tin wire. The solder joints should be smooth and shiny. No false welding or false welding. Adjust the temperature of the tin furnace to 270 ± 10 ℃. When the specified temperature is reached, the tin bar should melt. The melted molten soup should be shiny and free of impurities. Hold the tin wire in one hand, and the soldering iron in one hand, and lean the soldering iron on the pin. When the pin is hot, then rest the solder wire on the joint of the soldering iron and the pin. When the amount of tin is almost the same, remove the soldering iron and the tin wire . But then I often make the pins very hot, but the tin is not enough, and sometimes the tin is hung on the soldering iron and cannot flow.
The method of dipping the solder core wire with tin is to first dip the rosin alcohol with a soldering iron and then take the tin, and then lean the oblique edge of the soldering iron to the pin, and let the tin flow down and cool on the pin. However, the amount of tin is not easy to control, and I will often be pulled out of burrs. Adjust the temperature of the constant temperature soldering iron to the specified temperature (lead tin wire: 245 ± 10 ℃, lead-free tin wire: 270 ± 10 ℃). When the constant temperature soldering iron reaches the specified temperature, the solder core wire should be able to melt and the solder core No large amount of smoke is generated when the tin wire is melted.
No-clean tin wire After cutting the tin wire, check that the cross section is hollow with rosin flux in the middle. The standard specification of the solder core wire is to improve the company's quality operation standards, standardize the material inspection method, and ensure that the quality of the material meets the company and customer quality requirements. Visual inspection, the incoming materials should be intact and undamaged, and clearly marked. The tin content of the wire or strip should be clearly marked on the package. If it is a lead-free solder wire or strip, the package should be marked "lead-free"; visual inspection, the solder wire should be smooth and shiny. No oxidation and blackening. The surface must be free of oil, water and other dirt. Dust caused by the transport material and capable of being blown away by the air is acceptable. The diameter of the solder wire measured with a caliper should meet the requirements.
