G642 Leaded Solder Paste
G642 is a leaded solder paste developed by our company for high-precision SMT processes. Formulated with low-oxide Sn62.9Pb36.9Ag0.2 (Type 4 powder, melting point 183°C) alloy solder powder and ROM0 classified flux. The system incorporates high-performance thixotropic agents, providing superior wettability and continuous printability, suitable for fine-pitch components (QFP, etc.).
Features:
- No-clean type, minimal residue after reflow soldering, low corrosivity, high surface insulation resistance.
- Low volatile solvent system, wide operating window, good consistency in continuous printing, suitable for 0.3mm and finer pitch mounting.
- Good thixotropy, resistant to slumping during and after printing, reducing the occurrence of solder bridging/shorts.
- Good wetting performance, suitable for various reflow methods, resulting in full, good solder joints with high strength and excellent conductivity.
