Tin wire is a lead-free and environmentally friendly solder material, mainly composed of [external link removed] is mainly used in the electronic manufacturing field with high requirements for welding reliability, heat resistance, and environmental friendliness.Main purpose:
1.High density electronic assembly: suitable for manual or automatic soldering of miniaturized, high pin count components such as BGA and QFN.2.High temperature environment application: Due to its high melting point (227 ℃), it is suitable for components that need to maintain stable connections under high temperature conditions, such as high-power chips, power modules, automotive electronics, industrial control equipment, etc.3.Electronic products: widely used in consumer electronics, communication equipment, medical instruments, vehicle electronics, and other [external link removed] and manual welding: commonly used for repair, debugging, and manual welding operations in SMT assembly and small-scale production.Wear personal protective equipment:
1.Wear heat-resistant goggles or face shields to prevent solder from splashing into the eyes.(In case of eye contact: Immediately rinse with running water for at least 10 minutes)
2.Protective gloves to avoid burns.(In case of skin contact: Immediately wash with plenty of soapy water)
3.Wear a mask (to prevent inhaling metal oxide smoke)
Ensure good ventilation: Welding high-temperature tin wire will produce rosin smoke and metal oxides, which are harmful to health if inhaled for a long time.(It should be operated in a fume hood or an environment equipped with local exhaust devices; if conditions are limited, at least open windows and use fans to assist in smoke exhaust.)
