To address the mounting challenges of 01005 micro components, domestic solder paste brands have achieved stable printing and solder wetting of high-density solder pastes in openings below 0.3mm through the synergistic optimization of T4/T5 grade ultra-fine alloy powder, ROL0 grade ultra-low halogen control, and rosin-based active systems. Among them, the 8MNTTP/5RNTT series achieved over 92% solder joint coverage in actual tests on mobile phone motherboards, significantly outperforming conventional T3 powder solutions.
Published: 2009-04-21To address the frequent occurrence of cold solder joint defects on SMT production lines, this domestic solder paste, through optimized alloy powder ratio and flux activity design, achieves nearly 100% solder wetting rate on QFN/DFN devices while significantly reducing void rate. Its multiple product lines, including halogen-free, zero-halogen, water-washable and laser-compatible variants, cover different process requirements, making it a cost-effective anti-cold-solder-joint solder paste solution to replace imported SMT solder pastes.
Published: 2009-04-19The practical performance of high-activity solder paste in achieving nearly 100% solder wetting rate for fine-pitch QFN/DFN devices directly determines the success or failure of domestic solder paste brand selection. Based on the measured data of Jia Jinyuan LFP-JJY series halogen-free and lead-free high-temperature solder paste, this paper compares the differences in residue transparency, halogen content, and alloy powder particle size distribution among models including 8MQP/5RQ, 8MTSP/5RTS, and 8MNTTP/5RNTT in the reflow soldering solder paste process, providing a directly applicable domestic solder paste replacement solution for SMT production lines.
Published: 2009-03-30Communication motherboards have extremely high requirements for solder paste's wetting ability, residue transparency, and halogen control. The 8MNTTP/5RNTT series communication board solder paste launched by domestic solder paste brand Jiajinyuan contains only 100~200ppm halogen, with minimal and transparent residue. It is compatible with high-density packages such as QFN/DFN, and achieves high-reliability solder paste performance when paired with 00507BN/T5 ultra-fine powder. It has been batch-verified on 5G base station motherboards.
Published: 2009-03-08To meet stringent requirements in high-density PCB soldering such as fine pitch, high solder climb rate, and low void rate, multiple domestic halogen-free, lead-free high-temperature solder pastes compatible with T3/T4/T5 grade fine powder solder pastes are recommended, covering high-activity scenarios for QFN/DFN, precision placement in communications and consumer electronics, low-void thermal management for automotive lamps, and special models for laser dispensing. All products use 0307/305 alloy powders with a measured melting point of 217–227℃, balancing printability, wettability, and residue transparency.
Published: 2009-02-26The spherical solder paste made from spherical tin powder of domestic solder paste brand Jiajinyuan performs outstandingly in practical test scenarios such as nearly 100% solder climbing rate in QFN/DFN, extremely low void rate, transparent residue and water washability. Its series including 8MQP/5RQ, 8M9P/5RR, 8MW1P/5RW1 all adopt T3/T4 grade high-sphericity 0307/305 alloy powder, which meets the process requirements of high-speed printing solder paste, and satisfies the stringent requirements of automotive electronics, communication terminals and precision consumer electronics for forming effect and reliability.
Published: 2009-02-24The high rework rate of production lines often stems from poor solder paste wetting, high voiding rates, or uneven residue. This domestic solder paste achieves nearly 100% wetting coverage on QFN/DFN devices through the synergistic optimization of 0307/T4 alloy powder and ROL0 low-halogen formulation, significantly improving first-pass soldering yield. It is a highly adaptable domestic solder paste option for replacing imported SMT solder paste and reducing rework solder paste costs.
Published: 2009-02-16To 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: 2009-01-27Post-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.
