Advantages of Tin Lead Solder Bar
1: Oxidation solder bar
Soldering temperature lower than 300ºC, the surface seems like mirror. Short welding time and higher spreading ratio than the normal solder. Cause of the addition of anti-oxidant, the dross of the solder is only 1/5 comparing with the common solder bar, and the spot of solder joint is bright, which suitable for wave or handwork soldering with specification as Sn60/Pb40, Sn63/Pb37.
2: Low melting temperature solder bar
28ºC-180ºC low melting temperature solder bar is widely used in alarm security devices, lighting proof protective appliances, air-conditioner security warning device, temperature display materials and filled composites during mechanical processing.
