Lead-free solder wire and leaded solder wire are divided into two categories according to the environmental protection standards of solder wire. Recently, some customers have asked whether it is better to use lead-free solder wire or leaded solder wire? This problem is actually a matter of benevolence and wisdom, and it has a certain relationship according to different products and component materials.

There are many types of lead-free solder wires, but the main ones are tin-copper series and tin-silver-copper series. Among them, the lead-free solder wire with the composition of Sn99.3Cu0.7 is the most widely used, and is mainly used for the welding of electronic products with environmental protection requirements. Lead-free solder wire has good solderability, wettability, good expansibility, no-cleaning; full, bright, firm solder joints, neat and untangled coils; uniform flux distribution, less smoke and no spatter during welding, etc. Both manual welding and automatic wire welding machine welding are available, and the rosin content and wire diameter can be customized according to customer requirements. With the enhancement of everyone's awareness of environmental protection, lead-free solder products are more and more trusted by everyone, and their applications have also been greatly enhanced. Lead-free solder wire is enough to meet people's requirements for welding. The characteristics of lead-free solder wire are integrated so Don't worry about whether the lead-free solder wire is easy to use. If there is a demand for lead-free solder wire, you can find a manufacturer to prepare a lead-free solder wire that is suitable for components, production processes and materials. Try the samples and then make bulk purchases according to the actual situation.

Leaded solder wire is mainly made of tin and lead alloys with the addition of corresponding flux components. According to the different proportions of tin and lead, it is divided into various specifications such as common Sn63Pb37, Sn60Pb40, Sn55Pb45, Sn50Pb50, etc. Leaded solder wire is based on The production process is divided into rosin core solder wire, solid core solder wire, etc. Rosin solder wire can adjust the size of rosin according to the welding process to achieve a good welding effect. Solid core solder wire needs to be used together with flux. In lead solder The tin content in the wire has a certain relationship with whether the solder wire is good or not, but it does not mean that the higher the tin content, the better it is. Whether it is good or not depends on whether the choice of solder wire matches the actual welding product, and It is the operator's operating methods and operating habits.
