According to the International Chemical Safety Cards: Possible mechanical irritation of the respiratory tract occur solder Which is good, temporary repeated exposure may damage the lungs, causing benign pneumoconiosis (tin pneumoconiosis) but occupational hazards directory no direct reference to the content of the relevant tin are: Lead and its compounds (lead dust, lead fume compounds, not including tetraethyl lead, occupational diseases could lead to: Lead and its compounds toxic heavy non-ferrous metal smelting industry: tin furnace ingredients, tin fuming Tin Tin point hole means that after welding the outer hole. This now can cause high temperature solder wire welding process. bridge means associated solder joints as if the same bridge. Then you need to check whether the PCB line qualified, in addition to the aid activity is not strong solder wire and solder wire antioxidant brand, or solder advantages: melted only a small amount of residue no-clean type solder wire low viscosity, good fluidity, high weldability. most suitable for wave soldering process solder wire price |.
