Shengyi SI10U Sensor IC Substrate: High-Performance, Halogen-Free Material for Advanced MEMS Applications The Shengyi SI10U Sensor IC Substrate is a premium printed circuit board material engineered specifically for micro-electro-mechanical systems (MEMS) sensors. Designed to meet the demanding requirements of modern electronics, this substrate combines superior mechanical stability with excellent thermal and moisture resistance, making it ideal for high-reliability applications in automotive, consumer electronics, and industrial sectors. With a glass transition temperature (Tg) of 280°C and low coefficient of thermal expansion (CTE), SI10U significantly reduces warpage during manufacturing and operation—ensuring consistent performance under extreme conditions. Key Features: - Low CTE (Coefficient of Thermal Expansion): Minimizes stress-induced deformation in sensor packages - High Modulus: Enhances structural integrity and dimensional stability - Excellent Heat and Moisture Resistance: Maintains reliability in humid or high-temperature environments - Superior
PCB Processability: Compatible with standard fabrication techniques including drilling, plating, and soldering - Halogen-Free Composition: Environmentally friendly, compliant with RoHS and other global regulations - Tg280: Ensures thermal stability up to 280°C, critical for reflow soldering and long-term operational durability Detailed Description: MEMS technology integrates microscopic mechanical
Components such as sensors, actuators, and control circuits onto silicon-based chips using semiconductor fabrication methods. This enables mass production at lower costs while delivering enhanced precision, miniaturization, and energy efficiency compared to traditional mechanical systems. The Shengyi SI10U substrate serves as an essential platform for these advanced devices, offering unmatched compatibility with MEMS packaging processes. Its unique combination of physical properties—such as high Young’s modulus similar to iron, low density like aluminum, and thermal conductivity comparable to tungsten—makes it particularly well-suited for environments where thermal cycling, vibration, or chemical exposure could compromise performance. Unlike conventional substrates that may warp or degrade over time, SI10U maintains its shape and electrical integrity even under harsh operating conditions, extending device lifespan and reducing field failures. Use Cases: This substrate is widely adopted in automotive electronics—for example, in airbag deployment systems, tire pressure monitoring, and engine control units—where robustness and longevity are paramount. In consumer electronics, SI10U supports the development of next-generation smartphones, wearables, and smart home devices that rely on precise motion detection, environmental sensing, and voice recognition. Medical devices such as implantable sensors and diagnostic tools also benefit from its biocompatibility, reliability, and minimal signal interference. Whether used in aerospace-grade instrumentation or ruggedized industrial equipment, the SI10U substrate delivers consistent results across diverse application domains. User Feedback: Engineers and designers working with MEMS-based products consistently report improved yield rates and reduced post-assembly defects when using Shengyi SI10U. One product development manager noted, “The substrate’s ability to resist warpage during reflow soldering was a game-changer—it eliminated the need for costly corrective measures.” Another user highlighted its role in enabling thinner, more compact designs without sacrificing durability: “We were able to reduce overall module thickness by 15% while maintaining full compliance with automotive standards.” Frequently Asked Questions: What makes SI10U better than standard FR4 materials for MEMS substrates? SI10U offers a much lower CTE, higher modulus, and greater thermal resistance than typical FR4 laminates, which helps prevent delamination, cracking, or misalignment in sensitive MEMS structures during assembly and use. Why is halogen-free material important in sensor substrates? Halogen-free materials reduce the risk of corrosive gas emissions during processing or fire events, improving safety and environmental sustainability—especially crucial in automotive and medical applications. How does SI10U support high-volume manufacturing? Its excellent processability allows seamless integration into existing PCB fabrication lines, minimizing downtime and tooling changes while ensuring consistent quality across large batches. Is SI10U suitable for extreme temperature environments? Yes, with a Tg of 280°C, it performs reliably in both high-heat environments like engine compartments and cold climates down to -40°C, making it versatile for global deployment.
