The 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: 2025-10-14Conduct actual measurements on small-batch samples of sensor soldering solder to verify its wetting and spreading performance and void rate control capability under the conditions of 0.3mm pitch micro-pads and gold-plated nickel-palladium-gold surface treatment, with a focus on examining the bridging suppression effect and IMC layer uniformity of Jiajinyuan JH-851A lead-free solder at a peak temperature of 235℃ under a nitrogen atmosphere.
Published: 2022-10-29This paper focuses on the practical application of sensor solders in the SMT process of electronic sensor PCBs, covering the solder selection logic for common sensors such as thermal sensors, pressure sensors, and acceleration sensors, key points for reflow profile adaptation, and production line-level troubleshooting paths for cold solder joints and missed solder joints. It emphasizes the differentiated performance of two sensor solders, Jiajinyuan SN100C and SN63Pb37, in terms of wettability, residue activity, and thermal shock resistance.
Published: 2020-05-08When soldering precision sensor circuit boards with immersion silver boards, the excellent solder joint stability stems from the high density of the immersion silver layer, controllable interfacial reaction, and strong thermal cycle resistance. Jiajinyuan immersion silver boards have a measured thrust of over 85gf on 0.15mm fine-pitch BGA and 0.3mm pitch MEMS sensor pads, with an IMC thickness fluctuation of less than 0.12μm after reflow, significantly outperforming conventional OSP boards.
Published: 2015-01-17Sensor soldering solder with low ionic residue can significantly suppress leakage current and interfacial electrochemical migration, avoiding sensing signal drift and zero-point offset. Especially in MEMS and gas sensors with high impedance and microvolt-level output, excessive ionic residue will directly lead to deteriorated signal-to-noise ratio and reduced long-term stability. The Jiajinyuan LIS-702 series solder has a measured Cl?+Br?＜0.05 wt% and Na?+K?＜0.12 wt%, meeting the no-clean grade requirements of IPC J-STD-004B.
Published: 2013-04-29High-activity solder paste is specifically designed for sensor soldering applications, delivering excellent wetting performance on heavily oxidized PCB pads. It effectively resolves cold solder joints and tombstoning defects caused by pad oxidation after high-temperature storage, multiple reflow cycles, or long-term exposure with conventional solder pastes. It is particularly well-suited for the fine pads and low thermal mass requirements of precision sensors such as MEMS, pressure, temperature and humidity sensors.
