Lead-free solder and no-clean Flux are commonly used circuit soldering materials, which are indispensable in the electronics industry. Generally speaking, lead-free solders include tin-lead alloy solders and solders with antimony, silver, and copper. By adding these elements, the performance of the material can be improved.

      Generally, the welding wire used in the welding operation is added with no-clean Flux. This no-clean Flux is composed of active agent and rosin. The temperature during welding is very important. The most suitable temperature is 50 degrees higher than the melting point. The set temperature varies depending on the lead-free solder wire type, etc. Shenzhen Mingdeyuan lead-free solder products mainly include no-clean Flux, solder wire, welding rod, solder paste, etc. The welding methods include manual welding and wave soldering.

      The use of Shenzhen Mingdeyuan lead-free solder: According to different alloy compositions, the types of Shenzhen Mingdeyuan solder are also different. The alloy composition is Sn63/Pb37 solder, which has a relatively low melting point, high tensile strength, and wettability. Better; the alloy composition Sn55/Pb45 is commonly used in general electronic toys and electrical appliances; the solder with the alloy composition Sn45/Pb55 is mainly used in some welding places where the requirements are not very high, such as can making, fuse and automobile manufacturing. Now there are many types of solder, and the functions and uses are also different. It can be said that no matter what kind of metal equipment can be welded, the role of solder is very large.
