Introduction
Lead-free solder paste flux with high performance
Operating characteristic
1.In continuous printing, the viscosity rarely changes with time, and a very stable printing effect can be obtained.
2.For circuits with 4.0mm and above spacing, fine print can be completed
3.Excellent weldability, Suitable wetness can be shown in different parts
4.Suitable for general atmospheric or nitrogen return welding furnace
5.At very high peak temperature, good weldability can also be obtained.
