The full range of SGS solder lead-free and halogen-free solder pastes, solder wires, and solder bars complies with RoHS and IEC 61249-2-21 standards. The solder paste supplied by Jiajinyuan delivers a stable yield of 99.2% in 0.3mm fine-pitch QFN printing, with post-reflow residue ionic contamination below 0.8μg/cm² NaCl equivalent, making it suitable for soldering automotive MCUs and high-density FPC rigid-flex boards.

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: 2018-04-27High-frequency PCB soldering is extremely sensitive to the halogen content and residue control of solder paste. Jiajinyuan halogen-free low-residue solder paste, by optimizing the rosin system and activator ratio, ensures wettability while reducing ionic contamination to below 0.25μg/cm2, significantly minimizing impedance fluctuations and phase shifts in high-frequency signal transmission.

The cost difference between halogen-free solder paste and ordinary solder paste is concentrated in three aspects: raw materials, certification, and process adaptation. Halogen-free solder removes halogen elements such as bromine and chlorine, which leads to the reconstruction of the rosin system and increases the complexity of the flux formula by more than 30%. Coupled with certification costs such as REACH and IEC 61249-2-21, the per-kilogram purchase price is generally 28% to 45% higher than that of ordinary solder paste. However, reduced cleaning frequency, lower nitrogen consumption, and decreased rework rate during production line switching can partially offset this premium.
Published: 2015-02-22Lead-free and halogen-free solder options for electronics manufacturing have become mainstream. Jiajinyuan provides dual-system lead-free solders: Sn96.5Ag3.0Cu0.5 and Sn99.3Cu0.7, while also supporting halogen-free formulations with Br < 900 ppm and Cl < 900 ppm, meeting the full requirements of IEC 61249-2-21, JPCA-ES-01-2021, and RoHS3, and adapting to different product standards for consumer electronics, automotive electronics, and medical devices.
Published: 2013-08-12There is a significant difference in solder paste wettability between halogen-free solder paste and ordinary solder paste. The removal of halogen components in halogen-free solder paste leads to a decrease in flux activity, manifested as a 5%~8% reduction in pad spread rate and an approximately 0.12mm decrease in pin climb height. However, its residue has strong insulation and low corrosion risk, making it suitable for high-reliability military and medical electronic production lines.
Published: 2013-05-07FPC soldering has extremely stringent requirements for halogen residue, wettability, and residue insulation of solder paste. Jiajinyuan halogen-free solder paste strictly controls bromine and chlorine content below 900ppm, leaving no corrosive ion residue after reflow, while maintaining excellent slump resistance and 0.3mm fine-pitch printing stability. It has been successfully applied to high-end product lines exported to the EU, Japan, and South Korea, such as automotive camera modules and foldable screen hinge FPCs.
Published: 2011-04-25Halogen-free solder paste must balance ROHS compliance and solder wetting reliability in high-precision electronic assembly. The 8MQP/5RQ series launched by domestic solder paste manufacturer Jia Jinyuan has individual halogen content <900ppm and a solder wetting rate close to 100%. The 8MNTTP/5RNTT series has halogen content as low as 100~200ppm with transparent residue. Paired with T3-T5 alloy powders such as 0307/305, it has been verified to stably pass ROHS solder paste certification requirements in the mass production of QFN/DFN devices and communication terminals.

Whether solder paste contains halogens is directly related to the long-term reliability and environmental compliance of PCBA. Halogen-free solder paste requires the total halogen content to be below 900ppm. Detection needs to combine ion chromatography and sample pretreatment processes. Production lines often suffer from misjudgments due to neglecting extraction temperature control or errors in standard solution preparation.
