Why solder wire with rosin core from China?

solder wire with rosin core from China

What is solder wire with rosin core that is made in China?

Solder wire is the solders made made into a wire form, generally that comes in a wire diameter ranging from 0.6mm to 2.5mm, and the base metal is tin & lead alloy. While there are two options of the core to choose from, one is solid core and the other one is with rosin core. The solid core means the whole wire is compact and no flux was embedded in the core, while a solder wire with rosin core (made in China) means the solder wire is embedded with some rosin based flux as core. 

Why should we use a solder wire with rosin core (made in China)?

When we do soldering work with solder wire, a flux must be used together. Because the flux is with different types of additives and under heat, will help to solder wire to well melt down and during the soldering process it will also help to better clean the surface of the joining area in case it's already oxidized. So that means, when you use a solder wire with solid core, you have to prepare flux in separate to used together, but if we use a solder wire with rosin core already, then we don't have to prepare flux in separate. So inclusion, when you want to buy solder wire from China, it's more convenient that you buy a solder with rosin core.

About solder wire with rosin core made by us XF Solder China.

We use good quality rosin as base of the flux core, and it's a no-clean rosin core. That means after soldering by using our XF solder wire with rosin core, very little, non-corrosive residue is left, so no need to clean it. And the nominal percentage of rosin flux is 2.0% as standard, in case you need special percentage of rosin flux, we can also make for you.
