This series product is lead-free and extension flux, which is the mixture of high-quality imported rosin and high-purity benchmark extinction resin imported from Japan and special solvent as well as organic activator. A protective film without reflection will be formed on the welding joints of PCB board after using, without any toxicity. Even the PCB board is examined under bright lights such as ambient light, sun light and electron light, the reflection of light will not stimulate eyes and lead to eye strain. The residues on PCB board have extremely high surface insulation resistance (SIR) and fast drying effect.

FEATURES

1. Smooth extinction for welding spot, good weldability, full welding spot and good tin permeability.

2. A few residues, uniform film forming for PCB board and no hygroscopic property.

3. High insulation resistance; do no need cleaning after welding.

Application scope

Apply to: This product applies to large PCB board, welding with many welding spots, such as computer displays, main panel of TV, display screen and UPS.
