Kunshan tin slag recycling

Products in the electronics manufacturing process, essential for wave soldering process, welding quality electronic products play a key role; and wave soldering processes determine the characteristics of the welding process, there have been new liquid solder surface exposed to the air molten solder in a flow state in contact with oxygen in the air and constantly oxidized to form an oxide slag; solder dross solder alloy mainly a mixture of oxides with a large number of solder alloys, which continue to produce and accumulate on the surface of the molten solder alloy not only the liquid solder flow is affected, there may be contamination PCBA board, direct impact on product quality and reliability of solder, and solder alloy causing a huge waste. In the electronics manufacturing industry, with the gradual process of introducing lead-free soldering, lead-free solder alloy of high tin content gradually replace traditional solder alloy; lead-free solder has a higher content than many traditional lead solder, and thus easier oxidized to produce more dross With the extensive application of lead-free solder, the problem becomes more serious oxide slag, a waste rate of 30% -50%; welding quality and reliability has also been a considerable impact; How to reduce the production of tin oxide slag becomes a compulsory course in electronics manufacturing are facing! Product Attributes tin is a soft silver-white metal, a specific gravity of 7.3, a low melting point, is only 232 degrees, you put it into briquettes furnace, it will melt into a mercury-like liquid. Tin very soft, can cut it with a knife. Chemical properties of tin is very stable, not easily oxidized by oxygen at room temperature, so keep it shiny silver sheen. Tin toxic, people often put it in the brass-plated wall, to prevent warm water producing toxic copper patina. Shell also commonly made of tin toothpaste (toothpaste shells are two central layer of lead-tin made in recent years, China has gradually aluminum instead of tin toothpaste manufactured housing). Solder also contain tin, typically containing 61% tin, and some pewter half, but also some from 90% lead, 6% and 4% antimony tin. Other notes Contact Hotline: 15250218869 Electronics Co., Ltd.
