Lead-free solder is often the most common goal of a solder, is mainly used for general requirements for welding and repairs, depending on the amount of alloy, melting point, etc., use is also slightly different. Is characterized by good wettability, electrical conductivity, thermal conductivity, easy on the tin. Customized according to customer requirements% rosin content, no welding spatter. Flux distribution, no broken tin flux in the core phenomenon. Winding even no tie, fast on the tin, the residue is minimal. Tin wire diameter size from 0.6-3.0mm can be customized production. Less so solder, whitish higher probability of containing the smaller tin solder. Tin dust concentration 9.362mg / m3 in the work environment Which solder, tin pneumoconiosis occur. Clinically little cough, sputum, chest tightness and other symptoms of solder manufacturers, the majority of patients had no change in lung function. Today, I look at the specific solder temporary use on the human body. Generally as long as proper protection to the human body in a short time without apparent harm, most of the tin and its inorganic compounds are toxic items. But the local tin salt and a temporary contact with tin dust may cause lung tin solder happen Price, and can have the nerve poison! So if you need to pay attention to the temporary contact with tin dust protection, especially to maintain the respiratory tract, such as the local tin salts tin tetrachloride do not need to maintain contact with the skin!
