Welding process of lead-free tin bars and precautions in production
2022-05-19
Solder bars generally require employees to wear protective work clothes during production operations. In this way, many unexpected situations that occur when soldering lead-free tin bars can be avoided. In addition, employees are required to wear masks when using the solder bar, because the solder bar often produces undesirable phenomena such as splashing rosin and frying tin during welding. Wearing a mask can effectively prevent similar situations from happening.
Identification of solder wire quality
2022-05-19
Solder wire is divided into two types: lead-free and lead-free. The main components of lead-based solder wire are tin and lead. In recent years, environmental protection inspections have been very strict. For environmental protection requirements, many factories are using lead-free solder wire, but pure tin The difficulty of welding is increased, the fluidity is not strong, the diffusion performance is poor, the melting point of lead-free solder wire is high, the working temperature of welding is high, and the welding effect is slightly worse than that of lead solder wire, but these are based on the needs of your own factory. to decide.
How to distinguish the quality of solder wire

Second, touch it with your hands. High-quality solder wire will not easily get on your hands when you wipe it with your hands. If it is darker, it proves that the lead content is relatively high. Solder wire is generally not too hard, easy to swing when used, and has good ductility, so the softer it is, the better the purity is. Senior workers in the soldering industry can usually tell which solder wires are high-quality and which have high lead content with one hand.
What is the function of solder wire?
