In the electronics industry, the most commonly used solders are 6040 and 6337. This type of solder has a development history of several decades, and its manufacturing process is also relatively mature and complete. From this, it can be seen that to replace lead-containing solder, certain sufficient conditions must be met. Jia Jinyuan Solder paste manufacturer will analyze what these conditions are.

From the requirements of the electronics industry for soldered components, what needs to be taken into account is the ability to avoid damaging the characteristics of electronic components as much as possible. This is relatively common. Lead-free solder should have a melting point as close as possible to that of tin-lead Eutectic Solder. When the melting point is high, the solder will exceed the heat resistance temperature of electronic components, which will affect the Reflow Soldering process.

From this, it can be seen that using solder with a high melting point is not feasible. Second, from the perspective of process performance, it should have relatively good wettability on electronic components and PCB board coatings.

From the perspective of product reliability, it is necessary to be able to achieve relatively good soldering in the industry. The fracture toughness of the solder itself is also very important. When solder joints are required to have heat-resistant characteristics, because electronic products inevitably generate heat during use, this in turn leads to deformation.

Shenzhen JJY brand Solder Paste has gone through 12 years of R&D in solder paste and Solder Wire. Solder wire We are a manufacturer of solder paste and solder wire, offering lead-free solder paste, Leaded Solder Paste, solder rods, lead-free Flux paste, and related products.
