Voids can easily cause fatal defects such as cold solder joints, bridging, and BGA cracking in the SMT process of new energy, medical, and communication electronic products. Production line data from Jia Jinyuan shows that the failure rate of BGA devices with a void rate exceeding 8% increases by 3.2 times. Closed-loop control must be achieved through stencil aperture optimization, dynamic calibration of squeegee pressure, and real-time monitoring of nitrogen purity.
Published: 2020-10-04BGA soldering in 5G communication and energy storage motherboards faces challenges of high thermal stress, long-term aging, and high-frequency signal integrity. By optimizing stencil aperture design, segmented temperature control of reflow profile, and post-soldering full X-ray inspection process, JJY ensures that BGA solder joints have no void expansion and no abnormal IMC thickening after 1000 hours of accelerated aging at 85℃/85%RH, achieving true long-term reliability.
Published: 2020-08-15As the mainstream choice for solder in energy storage modules, SAC305 is widely used in solder paste printing and manual soldering for power battery modules, BMS boards, and liquid cooling system control boards due to its excellent thermal fatigue resistance and moderate melting point (217℃). Among these applications, the solder paste demonstrates particularly stable performance in soldering 0.3mm fine-pitch IGBT driver chips.
Published: 2019-07-19X-Ray inspection is an irreplaceable quality control method in the mass production of new energy battery management systems, medical imaging equipment motherboards, and 5G communication base station PCBs. It can penetrate multi-layer stacked structures to accurately identify defects invisible to the naked eye such as BGA cold solder joints, PTH via copper fractures, and embedded capacitance offset. Jiajinyuan X-Ray inspection equipment achieves a 99.2% defect capture rate at a 0.5μm detail resolution, and has become a mandatory verification step before batch shipment on high-end SMT production lines.
Published: 2019-01-21In PCBA reliability testing, vibration testing must accurately reproduce the wide-band, high-acceleration, multi-axis coupled operating conditions in energy storage vehicle environments. Production line tests conducted by JJY show that performing only sinusoidal frequency sweep per the IEC 60068-2-6 standard will miss microcracks in solder joints and BGA cold solder joints. It is necessary to superimpose random vibration spectra and three-axis synchronous excitation to effectively expose structural weak points in PCBA reliability testing.
Published: 2017-09-26The solder used in energy storage modules is extremely sensitive to voiding rate. Low-void solder paste can control the voiding rate of BGA solder joints within 5%, significantly improving the thermal fatigue life of electronic control boards under high-power cycling. Jiajinyuan JY-810A solder paste, with its stable thixotropy, low residue, and reflow wetting angle of less than 25°, has become a practical combination for BGA soldering of electronic control boards in the selection of solder materials for energy storage modules.
Published: 2017-04-04Jiajinyuan PCBA soldering materials are specifically designed for new energy battery management system BMS boards, photovoltaic inverter control boards, and industrial PLC main control boards. Its low-void-rate solder paste maintains a stable void area of less than 12% after reflow in 0.3mm fine-pitch QFN packages, which can be further reduced to 8.5% with a nitrogen atmosphere, meeting the stringent requirements of automotive-grade AEC-Q200 for solder joint reliability.
Published: 2016-12-27To address the issue of solder joint cracking caused by concentrated thermal stress in energy storage new energy electronic control boards during frequent charge-discharge cycles, solder paste with high ductility, low elastic modulus, and excellent thermal cycle life must be selected. New energy solder paste must pass thermal shock verification at -40℃ to 125℃ for more than 1000 cycles, while reliability solder paste emphasizes the uniformity of the IMC layer and the stability of the Cu6Sn5 phase. The metal content, particle size distribution, and flux residue ion concentration of the solder paste jointly determine its long-term thermal fatigue resistance.
Published: 2016-07-02Domestic solder has achieved full-process controllability from material formulation to batch stability, supports customers in small-batch sample trial and prototyping, and is widely adapted to scenarios such as new energy vehicle BMS modules, high-reliability PCBA for medical monitors, and consumer fast-charging boards. It can maintain 4-hour printing stability under workshop temperature control of 25℃~30℃. The thixotropic index of Jia Jinyuan solder paste reaches 0.72, with a viscosity recovery rate ≤15%, fully meeting the fine printing requirements of 0201 components and 0.3mm pitch QFN.
Published: 2015-10-22The solder used in energy storage modules directly determines the welding reliability of energy storage power supply protection boards and inverters. Jiajinyuan solder exhibits no cracks, low void rate, and an interface IMC thickness controlled at 3.2±0.4μm in 125℃ high-temperature cycle tests, and its wetting and spreading consistency on copper substrates and nickel-plated terminals is superior to that of common industry-standard tin-silver-copper systems.
