For solder paste, its ingredients are also quite diverse. So todayShenzhen JJYSolder paste manufacturerCome and lead the partners to analyze the functions of some elements in the solder paste together, namely antimony, bismuth and copper.

    Antimony. It is used to enhance tensile strength rather than to affect its lubricity. It can also effectively remove tin worms. Zinc elements should be avoided as much as possible and hot-dip galvanized metal composite materials should be used instead, because this type will directly affect the brittleness of the weld.

    Bismuth. It can relatively effectively lower its melting point andGet rid of the bad onesLubricity. When there is a relatively high amount of lead and tin, bismuth will cause a decrease in melting point, leading to the precipitation of crystals. The precipitated crystals will expand along the texture, and at low temperatures, common welding problems will occur.

    Therefore, when faced with the situation of using solder containing bismuth and then performing arc welding, what needs to be done is to increase the output power of the lead-plated alloy and further denitration the flue gas under load for the prefabricated components. When barium alloys are cooled, they expand, which can be used to counteract the thermal deformation mismatch stress field.

    Copper can play a role in lowering its melting point, thereby alleviating the fatigue of heat-resistant cycling equipment and being able toImprovement The lubricating performance of solder during melting. It can not only reduce the melting rate of copper from the plate, but also makeLiquid solderSome of the internal power transmission lines were relieved, and then metal compounds appeared. Still okayEnhanceThe tin crystal grows and develops well.
