Lead-free low-temperature solder wire is a low-melting lead-free environmentally friendly solder wire divided according to the melting point temperature of the solder wire. Refined with professional equipment and special craftsmanship. The proportion of the alloy is reasonable, and the flux is made of high-quality modified resin, organic activator and various additives, so that the low-temperature lead-free solder wire also has its special welding performance and application in the lead-free process.
Lead-free low temperature tin wire
Detailed parameters and characteristics of low temperature solder wire:
Product name: Low temperature lead-free solder wire
Composition: Sn42Bi58
Melting point: 138℃
Operating temperature: 190℃-200℃
Weight: 200g, 1000g standard (gross weight, including rubber wheel weight)
Packing: 10 rolls per carton (2kg/box, 1000G/box)
Wire diameter: 0.6mm 0.8mm 1.0mm
Features of low temperature lead-free solder wire:
1. Comply with ROHS environmental protection requirements.
2. Good solderability, good wettability and good expansibility.
3. Low melting point and low welding temperature, reducing thermal shock to components.
4. It can be used as rosin core or solid core (solid core models need to be used together with flux).
5. It is suitable for welding of electronic components that cannot withstand high temperature.
Sn42Bi58 lead-free low temperature solder wire is suitable for soldering heat sensitive components. It is widely used in staged welding (secondary welding) in the electronics industry, TV tuners, fire alarms, temperature control components, lightning protection periods, air conditioner safety protectors and other industries. When soldering, the temperature of the soldering iron tip is suitable to be controlled between 190-200°C, and the angle of the soldering iron tip is preferably 45-60o (vertical working surface). The tip of the soldering iron should be in contact with the component leads and the surface of the PCB pads.
Storage and shelf life of lead-free low temperature solder wire:
There are two types of lead-free low-temperature solder wires, one is rosin core, the other is solid core, and their storage methods and shelf life are different. Reduce the oxidation of the solder wire, and ensure that the packaging is not damaged, and the tin wire is not exposed to dust and other substances; in addition, the solid core tin wire can have an indefinite shelf life, and the lead-free low-temperature solder wire should be stored in a ventilated, dry and non-corrosive place. environment and identify it.
