Tin lead Soldering Flux

Tin lead Soldering Flux

Introduction

Lichuang tin-lead soldering flux, also called soft solder is configured based on the features of and exclusively used for the welding of tin-lead solders. Usually, this product appears colorless or orange (LC-102) and liquid. It suits itself for soldering dual and multi-line circuit board and electronics, computers, telecommunication, household appliances, and more.



Advantages

1. The tin-lead soldering flux has little smell, not contaminating the working environment.

2. With this soft solder, there is less residues left on the work piece, contributing to the clean-free property.

3. It has other advantages like favorable wettability, preferable fluidity, high impedance, etc.

4. Besides, Lichuang tin-lead soldering flux passes silver chromate test, copper mirror test, electro-migration and copper plate corrosion test, thus very reliable and effective.
