取一段报废的屏蔽线,将屏蔽网从电线中取出,压扁后在其表面蘸上一层松香混合液,待松香凝结后即可成为一根备用材料线。将这根屏蔽网一端对准要拆下的集成块焊点的一头,用无焊锡的电烙铁,通电将烙铁头加热到焊接时的温度,然后将热量逐渐传递到网上,使焊锡熔化而粘吸在网。如一次吸不干净, Take a scrapped shielding wire, remove the shielding net from the wire, and flatten it with a layer of rosin mixture on its surface. After the rosin is condensed, it can become a spare material wire. Align the end of the shield with one end of the solder joint to be removed and use a soldering iron without solder to energize the tip to the temperature at which it is soldered. The heat is then gradually transferred to the web to melt the solder. Sucked in the net. If a suction is not clean,
