Lead-free solder paste product characteristics
1. Adapt to long-term printing (more than 6 hours).
2. High-intensity antioxidant capacity.
3. It has good viscosity and thixotropy, and it has extremely long viscosity time and is not easy to collapse.
4. Has a very high insulation resistance, no need to clean.
5. It is not easy to produce tiny solder balls after soldering.
V series no-clean lead-free solder paste is a solder paste that is developed according to IPC and JIS and other international standards to meet future environmental protection requirements. It adopts new rosin resin and composite anti-oxidation technology, and selects low-oxidation spherical solder alloy. It is made from powdery and chemically stable paste-like environmentally friendly flux.
Suitable for all kinds of precision welding in the electronic assembly process SMT production. Alloy series no-clean lead-free solder paste
