Addressing the industry pain point that solder joints on new energy electronic control boards are prone to cracking and have insufficient reliability under high-low temperature cycling conditions, Jiajinyuan has launched a variety of halogen-free and lead-free high-temperature solder pastes, covering segmented scenarios such as high solder climb for QFN/DFN, low void rate, zero halogen, and laser welding. Its 0307, 305 and other alloy systems at 240

Under the measured condition of 8 hours of continuous wave soldering operation, the solder dross output can be reduced by 42% to 58%, significantly extending the maintenance cycle of the solder pot and reducing the frequency of manual dross removal.
Published: 2025-08-18Medical electronic equipment has extremely stringent requirements for the purity, ionic residue and long-term reliability of solder materials. With its strictly controlled metal composition, low halogen content and batch stability, ISO solder materials have become the first choice for SMT production lines of implantable and monitoring devices. Jiajinyuan ISO solder materials have passed the biocompatibility pre-assessment of IEC 60601-1 Appendix A. In actual production lines, the ionic residue on the board surface after reflow is <0.85μg/cm2, and the copper mirror corrosion test shows no discoloration for over 72 hours.
Published: 2025-01-15When soldering communication base station motherboards with high-frequency boards, it is necessary to cope with long-term cyclic working conditions from -40℃ to +85℃. Jiajinyuan optimized solder paste selection, stencil aperture compensation, and segmented temperature control of the reflow soldering profile, reducing the solder joint void rate to ≤8%. After 2000 thermal shocks, the impedance fluctuation remains <3%, ensuring the stability of 5G millimeter-wave signal transmission.

Through dual-track synchronous visual positioning, 0.02mm-level Z-axis closed-loop compensation, and a gradient temperature zone control system, Jiajinyuan equipment controls solder joint offset within ±12μm in mass production, effectively addressing typical failures such as tombstoning, cold solder joints, and uneven pad wetting during 01005 component soldering.
Published: 2024-08-21Automotive electronic solder maintains the mechanical strength of solder joints within a wide temperature range of -40°C to 150°C, and shows no microcracks after random vibration tests at 20G acceleration and 10Hz–2kHz, meeting the dual requirements of temperature resistance and vibration resistance for automotive electronic solder in high-reliability scenarios such as ADAS controllers and BMS main control boards.
Published: 2024-06-29Low-smoke solder wire for connector soldering is designed for high-volume automated soldering lines, addressing the pain points of traditional solder wires such as heavy smoke, excessive spatter, and poor wettability. It significantly reduces TVOC concentrations in the operation area while ensuring high electrical conductivity and mechanical strength. Compatible with automatic wire feeders for wire diameters ranging from 0.3 to 1.2 mm, it has achieved stable continuous feeding for 8 hours without downtime on customer production lines of Jiajinyuan.

Halogen-free solder paste stands out in preventing excessive dissolution of the gold layer, reducing leakage current during ICT testing, and improving long-term reliability. Jiajinyuan's halogen-free solder paste has been validated on multiple high-end HDI board production lines, demonstrating stable printability under 0.3mm pitch QFN and 0.4mm BGA packages, along with an actual void rate of <8%.
Published: 2023-07-11The R&D of solder ODM focuses on the welding pain points of thick copper boards and high-frequency boards. By adjusting the activity of the rosin system, the sphericity and particle size distribution of metal powder, as well as the viscosity and thixotropy of the carrier, it improves the melting and spreading ability without sacrificing printing accuracy, and solves production-line-level problems such as insufficient wetting caused by fast heat dissipation of thick copper and residual ion migration caused by sensitivity to dielectric loss of high-frequency boards.
