Solder paste selection for SMT factories must match production line equipment, component packages, and reliability requirements. Among domestic solder pastes, the Jiajinyuan series covers hard requirements such as over 90% solder wetting for QFN, low voids in automotive lamps, and no solder balls for laser dispensing. SMT solder paste parameters such as 0307T4 alloy with a melting point of 221–227°C, ROL0 halogen <500ppm, and translucent rosin residue have been batch-verified on mobile phone motherboards and communication modules.
Published: 2009-04-07Addressing the SMT solder paste selection challenges faced by small and medium-sized electronic processing plants, this article directly targets real production line pain points and recommends multiple domestic solder pastes featuring high solder climb rate, low voids, zero halogen, or ultra-low temperature characteristics. These pastes cover scenarios including QFN/DFN precision placement, automotive lighting thermal management, stainless steel and aluminum welding, and laser jet dispensing, while balancing solder paste stability, cleaning costs, and reflow window adaptability for factories.
