The global supply chain volatility in 2020 significantly impacted solder paste supply, prompting some manufacturers to accelerate localized production layouts to cope with market uncertainty. Industry trends show that demand for solder paste continues to grow, but supply stability faces challenges, and enterprises need to strengthen localized capabilities and industrial chain coordination.
The Jiajinyuan technical team provides on-site resident services at the customer's SMT production line, conducting full-process diagnosis and process optimization for typical soldering defects such as solder bridging and tombstoning. Relying on precise selection and parameter matching of various halogen-free and lead-free high-temperature solder pastes including 8MQP/5RQ and 8MNTTP/5RNTT, combined with 030
Jiajinyuan 5RLJ laser solder paste is optimized specifically for laser heating soldering scenarios. It adopts a synergistic design of rosin-based systems with multiple specifications of high-temperature alloy powders including 0307/105/305 and 00507BN, delivering stable performance with bright solder joints and no solder ball spattering within the 240–260℃ soldering window.

In 2018, a trend of solder paste formula optimization emerged in the electronics manufacturing industry, and enterprises began to pay attention to the application scenarios of environmentally friendly and low-residue solder pastes. With increasingly strict environmental regulations and rising industry demand for high-precision manufacturing, solder paste technology is gradually developing in the direction of low harmful substances and high stability.
The 5000㎡ standardized factory building accommodates 96 production lines, fully supporting the large-scale and stable delivery of multiple series of halogen-free and lead-free solder pastes. The elastic release capacity during peak seasons has been significantly improved, and the average customer delivery cycle has been shortened by 3~5 working days, especially ensuring the solder climbing rate and void requirements for communications, automotive electronics, high-precision consumer terminals, etc.
The Jiajinyuan R&D team has been continuously optimizing the formulation system in response to solder performance bottlenecks, and has developed 12 major halogen-free and lead-free solder series covering the full temperature range of high, medium, low and ultra-low temperatures. Its domestic high-end solders have achieved breakthroughs in key indicators such as QFN/DFN solder wetting rate, low void rate for automotive lamps, and no solder balls in laser welding.
