SAC305 solder paste is the mainstream lead-free solder paste. Its melting point of 217°C and soldering window of 235–255°C are compatible with most reflow processes. Domestic solder paste brands such as Jiajinyuan LFP-JJY5RQ-305, LFP-JJY5RR-305 and LFP-JJY5RNTT-305 stand out in halogen control, wetting ability and void rate, balancing high activity and low residue, and have become a reliable alternative for QFN/DFN packaging, automotive electronics and other scenarios.
Published: 2009-03-22Lead-free solder paste and leaded solder paste have essential differences in melting point, soldering temperature, halogen content and applicable scenarios. Domestic solder paste brands such as Jia Jinyuan have covered the full range from zero-halogen high-temperature to ultra-low-temperature products. Their 0307/305 alloy powder T3-T5 specifications perform stably in QFN solder wetting rate, void control and laser welding adaptability, providing a reliable choice for production lines to replace leaded solder paste.
