Temperature control of SN99.95 wave soldering: generally low control, for lead-free solder bar, its normal service temperature is 250-260℃. The furnace temperature was measured with a thermometer to evaluate the furnace temperature uniformity. In the process of wave soldering, the amount of tin in the tin bar will continue to decrease, when reduced to a certain extent, new tin should be added in time. To maintain the liquid level of tin and reduce the oxidation of tin due to tin wave drop.  The tin bars produced by our company are made of high-quality and high-purity tin raw materials. The tin bars produced by our company are suitable for various welding, with fast welding speed and good quality, and are well received by customers.
