Medical electronics include products such as patient monitors, color ultrasound systems, surgical robots, and wearable medical devices. These devices integrate high-density micro components and FPC flexible printed circuits, and have stringent requirements for solder joint reliability, signal stability, ionic residue, and batch traceability.
Published: 2026-08-24The solder used for Jiajinyuan sensor welding adopts a halogen-free formula design, meets the requirements of the IEC 61249-2-21 standard, has an ionic contamination value of post-welding residue lower than 0.5μg/cm² NaCl equivalent, can pass the high-reliability verification of medical sensors without cleaning, and is especially suitable for low-temperature welding scenarios of tiny heat-sensitive components such as platinum resistors and MEMS pressure cores.
Published: 2025-10-14Medical 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: 2025-01-15Circuit board soldering faces multiple challenges of high reliability, fine pitch, and heat-sensitive components in the medical, communication, and new energy sectors. Based on practical production line experience, this paper focuses on key processes such as solder paste selection, stencil aperture design, reflow profile optimization, and BGA rework, emphasizing solder joint wettability, void rate control, and cold solder joint identification methods. All parameters are derived from measured data from Jia Jinyuan production lines, without theoretical deduction.
Published: 2023-01-22Voids 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: 2020-10-04X-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: 2019-01-21Domestic 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: 2015-10-22Reliability testing of PCBA for medical communication applications must comply with stringent standards such as IEC 60601-1 and AAMI TIR18. Its PCBA reliability test items cover temperature cycling, highly accelerated life testing, vibration and shock, and damp heat with bias. For each test, stress parameters must be set based on real production line failure data. Production line measurements by Jia Jinyuan show that for BGA solder joints, a cracking rate exceeding 3% after 500 temperature cycles from -40°C to +85°C is deemed a process red line.
Published: 2015-06-27Leveraging 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: 2014-09-13Gold-plated board soldering undertakes high-reliability connection tasks in the manufacturing of medical and precision instrument PCBs. Its surface process must balance solderability, corrosion resistance, and long-term signal stability. Gold-plated board soldering is particularly suitable for scenarios requiring micro pads, high-frequency devices, and low contact resistance. Gold layer thickness control, nickel barrier integrity, and reflow parameter matching are key bottlenecks for mass production yield.
