Tin rod is a product of soldering tin, tin rod can be divided into lead tin rod and lead-free tin rod, both of which can be used for circuit board welding. Tin rod pure tin manufacturing, its wetting and fluidity is better, easy to tin. The solder joint is also bright and full. Add sufficient amount of antioxidant elements, antioxidant ability is strong. Tin bar is an indispensable solder in the electronic manufacturing industry, but because of various reasons, there are more waste tin bar. Therefore, the tin rod has the necessity of recycling. Because you're in short supply of tin. Waste tin rod will waste a lot of tin resources, tin rod recycling can be as much as possible to improve the utilization of tin to the maximum. Waste tin rod has a certain pollution to the environment, into the human body will affect the health.

 

1. The slag output after melting is less than that of ordinary solder, and it has excellent oxidation resistance; the use of high purity electrolytic solder can reduce the harmful impurities, and effectively avoid the welding problems caused by harmful impurities such as bridge, tip, poor wettability.

2, the viscosity of the tin rod is low, the fluidity is good, the weldability is high, the tin is uniform and fast, the cable protection tube, the bentonite waterproof blanket tin furnace temperature is lower. Slow down the speed of solder leaching phenomenon, effectively inhibit the dissolution rate of copper on the circuit board, extend the use time of solder in the furnace.

3. The solder joint of tin bar is bright and the tin slag is very little, which can reduce the product cost and improve the production efficiency.

4, due to the oxidation inclusion is very little, can minimize the tip, bridge phenomenon, welding quality is reliable, bright and full solder joint. Effectively prevent tin phase transition and whisker phenomenon in solder. Avoid the problems such as brittle solder joints after welding and fire jumping, short circuit and noise caused by whisker. Especially after the miniaturization of SMC/SMD, more attention should be paid to whisker interference.

Generally speaking, tin resources are relatively scarce. Waste tin rods and other waste a lot of tin resources, tin rod recycling can as far as possible to improve the utilization of tin to the maximum, so as to make the best use of everything.
