In 2026, the SMT solder market is experiencing structural growth driven by demand from automotive electronics, AI servers, and high-reliability military applications. Leading domestic and international enterprises, including Senju Metal Industry Co., Ltd., Shengmao Technology, Guangdong Yixinfeng Intelligent Equipment Co., Ltd., and Shanghai Kaibo, are accelerating their deployment of high-reliability SMT solder product lines such as lead-free high-temperature solders, low-void solder pastes, and nitrogen-compatible fluxes. R&D investment has increased by 18% to 25% year-on-year, and some enterprises have already obtained AEC-Q200 automotive-grade certification and entered the supply chain for NVIDIA's GB200 liquid-cooled servers.
Published: 2026-03-04For soldering gold-plated boards, it is necessary to balance the thickness of the pad gold layer with the activity matching of the flux to avoid black pad, cold solder joints, and excessive IMC growth. Jia Jinyuan's gold-plated board soldering solution has achieved a soldering defect rate below 0.3% in aerospace modules and medical equipment, with the key lying in the collaborative implementation of solder paste selection, reflow profile gradient control, and an oxygen content ≤100ppm under a nitrogen atmosphere.

Jiayuan's high-reliability halogen-free formula, by optimizing the SnAgCu alloy ratio and active flux system, keeps the IMC layer thickness stably at 3.2±0.4μm after 500 cycles of thermal shock from -40℃ to 85℃, completely avoids electromigration failure caused by halogen corrosion, and significantly improves the service life of industrial control motherboard solder in harsh scenarios such as rail transit and power monitoring.
Published: 2020-07-01Solder for 5G equipment must maintain zero solder joint cracking under complex operating conditions such as high-frequency vibration, wide temperature cycling, and high humidity and salt spray. Jiajinyuan's halogen-free high-reliability solder, through optimizing the SnAgCu main alloy ratio and the compounding of nano-scale active flux, achieves a solder joint shear force attenuation of <8% after 500 cycles of thermal shock from -40°C to +125°C, with a halogen content of <900ppm, fully meeting the long-term reliability requirements for 5G equipment solder in high-density interconnect scenarios such as 5G base station RF modules and millimeter-wave antenna arrays.
Published: 2018-04-27Leveraging its solder ODM R&D capabilities, JJY has developed solder pastes and preformed solder sheets with low voiding rate, zero halogen, and high-temperature reflow resistance for scenarios such as medical equipment, new energy vehicle electronic control, and high-reliability industrial modules. Their solder joint thrust reaches over 85MPa, and the IMC layer thickness is controlled within the range of 1.2～1.8μm, meeting the dual certification requirements of ISO 13485 and AEC-Q200.
Published: 2014-09-13Automotive electronic solder must maintain zero solder joint cracking under wide temperature range from -40℃ to 150℃, high vibration and long-life operating conditions. Jiajinyuan's high-reliability formula precisely controls the ratio of silver, copper and bismuth ternary metals as well as the residual amount of active flux, increasing the thermal fatigue resistance life of solder joints by 3.2 times and reducing the drop impact failure rate to below 0.008%, fully meeting the AEC-Q200 automotive grade requirements.
Published: 2011-12-18The nitrogen reflow process significantly improves solder joint wettability and oxidation suppression in the soldering of thick copper boards and high-frequency boards. Especially for thick copper substrates of 2oz or above, which have large heat capacity and slow heating, when paired with JJY dedicated solder paste, the void rate can be stably controlled within 8%. Meanwhile, it prevents thermal delamination of high-frequency dielectric layers. This process has been batch-verified on multiple production lines for military products and base station RF modules.
Published: 2011-08-22Communication 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 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.
