Covers solder paste requirements across the entire stage from R&D prototyping to mass production. Domestic solder paste brand Jia Jinyuan offers 15 specialized product series, ranging from zero-halogen ROL0 grade 8M9P/5RR solder paste for automotive lighting, to 5RG solder paste made with ultra-low-temperature In52Sn48 alloy, and further to the 5RLJ series compatible with laser jet valves. The full-stage solder paste solution supports near-100% wetting rate for QFN, extremely low void rate, water-wash compatibility, and direct soldering on stainless steel and aluminum materials, truly enabling single-vendor coordination and seamless switching for SMT solder paste selection.
Published: 2009-01-31To address production-line pain points such as prone solder joint failure, poor solder wetting, high void rate, and excessive halogen residue under high-temperature operating conditions, domestic temperature-resistant solder paste has achieved stable adaptation to reflow windows from 235°C to 260°C. The 8MQP/5RQ series achieves a solder wetting rate of over 95% on QFN/DFN devices, while the 8M9P/5RR series supports automotive lighting thermal management modules with 0 ppm halogen and an extremely low void rate. Multiple high-temperature solder paste models form a closed process loop with domestic stencils, jet dispensers, and nitrogen reflow ovens, truly resolving the bottlenecks that have hindered the deployment of domestic solder paste in high-reliability scenarios.
Published: 2009-01-29To address persistent production line issues such as solder joint cracking, cold solder joints, and poor solder wetting under vibration conditions, we recommend a range of field-tested, high-reliability solder pastes covering specialized scenarios including zero-halogen, low-void, high-wetting, water-washable, and laser-specific formulations. Among these, the 8M9P/5RR series achieves 0ppm halogen content and <1.5% void rate, while the 8MQP/5RQ series delivers a 98% solder wetting rate on QFN devices. Domestic solder pastes are now fully compatible with high-vibration environments such as automotive electronics, communication modules, and industrial controllers.
Published: 2009-01-27The rapid aging speed of solder paste directly affects SMT printing yield and reflow soldering consistency. Domestic anti-aging solder paste must balance halogen content, alloy powder particle size distribution, and rosin matrix stability. For example, the 8MNTTP/5RNTT series contains 100~200ppm ultra-low halogen, is compatible with T3-T5 grade 00507BN alloy powder, and has been tested on mobile phone and fingerprint lock production lines, with a viscosity change of <8% after 72 hours, significantly outperforming conventional domestic SMT solder paste.
Published: 2009-01-25Frequent solder paste clogging in stencils directly affects the efficiency and yield of SMT production lines. By optimizing the particle size distribution of alloy powder, the rheological properties of the rosin carrier, and the control of halogen residues, domestic anti-clogging solder paste achieves stable release and high solder wetting rates in fine-pitch printing applications such as QFN/DFN. A typical example is the 8MQP/5RQ series T4 powder paired with 0307 alloy, which balances printability and reflow performance, making it a cost-effective alternative to imported printing solder paste.
Published: 2009-01-23Domestic solder paste with clear printing and forming profiles must balance thixotropy, powder distribution, and reflow wettability. The Jiajinyuan 8MQP/5RQ series achieves high-resolution printing while delivering near-100% solder fillet climb rate on QFN packages. The 8MNTTP/5RNTT variant, with its ultra-low halogen content of 100~200ppm and T5-grade fine powder, is tailored for high-precision consumer electronics. These solder pastes with excellent forming performance have been batch-validated on SMT production lines, making them a reliable domestic alternative to imported SMT solder paste.
Published: 2009-01-21Post-welding insulation impedance compliance depends on the ionic cleanliness of solder paste residues and the compactness of the formed film. Domestic high-insulation solder pastes, through strict halogen control (ROL0 grade <500ppm), optimized rosin matrix and T4/T5 fine powder ratio, achieve 70%~100% solder wetting rate for QFN/DFN while ensuring the impedance between reflow solder paste joints is >10^9Ω. Series including LFP-JJY5RNTT, 5RR and 5RLJ have been mass-applied in communication module and automotive LED production lines.
Published: 2009-01-19Lead-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.
Published: 2009-01-17The choice between no-clean solder paste and water-washable solder paste must be closely aligned with the actual production line conditions. For example, when QFN solder wetting requirements are close to 100%, the 8MQP/5RQ series should be prioritized. For low-voidage scenarios such as automotive lighting, halogen-free 8M9P/5RR must be used. Water-washable solder pastes like 8MW1P/5RW1 are suitable for cost-sensitive production lines equipped with cleaning equipment. Domestic solder pastes now cover the full spectrum from ultra-low-temperature In52Sn48 to laser-specific 5RLJ. The key lies in matching the process window with reliability requirements.
Published: 2009-01-15When selecting solder paste for SMT engineering, it is necessary to closely align with the actual needs of the production line. Domestic solder paste has already demonstrated strong competitiveness in QFN solder climbing rate, halogen control, void rate, and adaptability to special processes. For example, the 8MQP/5RQ series achieves a solder climbing rate close to 100%, while the 8M9P/5RR realizes zero halogen and extremely low void rate. Engineering solder paste selection must be comprehensively evaluated based on alloy melting point, residue characteristics, and equipment compatibility.
