Desoldering process of in-line components

【Summary Description】 The desoldering process for the flat/cylindrical in-line assembly is shown in Figure 35. First, clean the pad of contamination, such as oil, oxide, flux residue, etc., Then adjust the temperature of the soldering iron to about 315 ℃, install the heat-driven soldering head with a special tool, wipe the soldering iron mouth with a sponge, and apply solder. Then, gently touch the pad to be cleaned with a soldering iron. After the solder melts, use a soldering iron to suck off the excess solder. Leave the soldering iron pad and work in a vacuum for 2 seconds to ensure that all molten solder is sucked into the soldering iron cavity. Repeat the tin suction operation to thoroughly clean all gaskets. The above method is applicable to vertical pins, partially bent pins, and fully bent pins. For bent pins, a straightening process should be added. In addition to tin absorption, tin absorption can also be removed with tin absorption tape. It is necessary to maintain and clean the welding head. Careful maintenance of the welding head can ensure good heat conduction at the lowest temperature and complete the welding. This not only reduces the damage to the surrounding materials, but also greatly extends the service life of the soldering iron. After removing the soldering iron, re-tin the soldering tip and put it back in place, and clean the soldering pad. The soldering iron needs to be cleaned regularly, as shown in Figure 36. It is worth noting that after cleaning the "S" plug, brush a layer of mineral oil on the surface to prevent tin.
