Which type of solder wire is called active solder wire?

Which kind?Solder wireIs it called active solder wire? Many people know that there are many types of solder wire, and the production process conditions required also fall into two categories: one is solid core, and the other is hollow core with rosin. Personally, I think the latter is directly used during soldering, which is much more convenient and has a wide range of applications. Then why is solder wire also called active solder wire? Let's pay attention and learn more below

Active solder wire actually refers to solder wire with added active agents, which is more conducive to soldering. The active agent in the active solder wire is designed to enhance the auxiliary heat conduction of the solder wire during the soldering process, remove oxidation, reduce the surface tension of the soldered material, remove oil stains on the surface of the soldered material, and increase the soldering area.

The main components of solder wire: Solder wire is not pure tin but a lead-tin alloy, made into hollow filaments, with rosin or other fluxes inside,Such as water-soluble resins, etc. Solder wires are classified into two major categories: those without flux cores and those with flux rosin cores. The types of flux rosin can be further divided into:Rtype(Inactive)RMA(Moderate and sexual)The melting points of solder wires vary depending on their alloy compositions.
Types of lead solder wire:

1.63/37Tin wire/6337Solder wire(Sn63/Pb37)

2.No-wash tin wire/No-wash solder wire(There is no need to clean the weld points after welding)

3.High-temperature tin wire/High-temperature solder wire(280Welding at temperatures above a certain degree)

4.Rosin tin wire/Rosin solder wire(Flux<1.6%)

5.Solid core tin wire/Solid solder wire(The solid core contains no flux) The soldering on the circuit board is composed of tin and lead.
The characteristics of leaded solder wire: electrolytic material, bright solder joints, good wettability, and easy to solder. Tin wire/The diameter of the tin wire can be customized according to customer requirements(0.5-3.5mm). Composite flux, no spatter during welding, can be customized according to customer requirements. The flux is evenly distributed, and there is no phenomenon of flux breakage in the wire core. The winding is neat, without knots, easy to weld and operate, and has high work efficiency .

Types of lead-free solder wire:

1.Tin-copper lead-free tin wire/Lead-free tin wire(Sn99.3Cu0.7)

2.Tin-silver-copper lead-free tin wire/Lead-free tin wire(Sn96.5Ag3.0Cu0.5)

3.0.3Lead-free silver tin wire/Lead-free tin wire(Sn99Ag0.3Cu0.7)

4.Lead-free tin wire for rosin/Lead-free tin wire(Flux content1.6%)

5.Solid core lead-free tin wire/Lead-free tin wire(It contains no flux components)

Lead-free solder wireFeatures: Made of pure tin, it has good wettability, electrical conductivity and thermal conductivity. The flux is moderate, ensuring no spatter during welding. Customized according to customer requirements. The flux is evenly distributed, and there is no phenomenon of flux breakage in the wire core. The winding is neat, without knots, easy to weld and operate, and has high work efficiency.
