Step into Jiuxi Testing
Shanghai Jiuxi Testing Technology Co., Ltd. Below referred to as "Jiuxi Testing," we are a third-party testing and verification service provider specializing in the semiconductor and integrated circuit industry. Headquartered in Pudong New Area, Shanghai, we focus on delivering professional technical services in failure analysis (FA), material analysis (MA), and reliability assurance (RA) for four strategic emerging sectors: automotive electronics, rail transit electronics, low-altitude flight electronics, and artificial intelligence (AI) chips. As a technology-driven professional service company, Jiuxi Testing upholds core values of objectivity, fairness, and precision, providing comprehensive quality assurance and technical support throughout the entire semiconductor supply chain—from chip design to end-user applications.
1. Strategic Positioning: Focusing on High-Reliability and High-Security Application Scenarios
As semiconductor technology advances to more sophisticated processes, chip applications are becoming increasingly complex, raising reliability and security requirements to unprecedented levels. JiuXi Testing precisely targets four high-barrier fields:
1. Automotive Electronics Field
The rapid advancement of the "four new transformations" in automobiles—electrification, intelligence, connectivity, and sharing—has led to a significant increase in both the quantity and value of chips used per vehicle. Automotive-grade chips must meet stringent standards such as AEC-Q100, encompassing dozens of evaluation criteria including temperature cycling, humidity testing, and electrical performance. JiuXi Testing provides comprehensive reliability testing and failure analysis services for automotive MCUs, power semiconductors, sensor chips, and more, based on automotive-grade standards like AEC-Q100/Q101. Leveraging its integrated capabilities in defect localization, sample preparation, and material characterization, the company precisely identifies microscopic root causes of failures, helping customers achieve a closed-loop quality management system.
2. Rail Transit Electronics Field
Rail transit equipment operates continuously in harsh environments characterized by high vibration, wide temperature variations, and strong electromagnetic interference, where electronic system failures can directly endanger train safety. Rail transit electronic devices follow strict fail-safe design principles, imposing extremely high requirements on component service life and process quality evaluation. JiuXi Testing provides failure analysis at both board and component levels, reliability life testing solutions, as well as development and implementation of reliability enhancement strategies tailored to the unique operational conditions of rail transit applications. By identifying failure modes, distinguishing failure mechanisms, and tracing root causes, we offer customers design and process improvement recommendations to prevent recurring failures.
3. Low-altitude flight electronics field
As a national strategic emerging industry, low-altitude economy encompasses new types of aircraft such as drones and eVTOLs (electric vertical takeoff and landing vehicles), whose core electronic components—including avionics systems, flight control computers, and navigation chips—require extremely high reliability. Low-altitude aircraft face complex environmental stresses, including atmospheric neutron radiation, drastic pressure changes, and vibration and shock, making single-event effects in chips particularly prominent among failure modes. JiuXi Testing offers comprehensive testing, verification, and analysis services for low-altitude aviation electronics across the entire industrial chain—from chips to components to complete end products—covering environmental reliability testing, failure analysis, and material performance evaluation.
4. AI Chip Field
The explosive growth of AI computing power has driven AI chips—including GPUs, AI accelerators, and high-performance SoCs—toward higher power density and more complex system integration. As a critical component of quality control, AI high-computing-chip testing technology plays a central role in verifying chip performance and reliability. JiuXi Testing offers AI chip customers comprehensive failure analysis and reliability verification services, including analysis and testing of high-density interconnect boards (HDI boards), covering the full lifecycle of quality management from chip design validation to mass production deployment.
II. Core Technology Service System
JiuXi Testing has established three core technical service divisions focused on semiconductor chip quality and reliability:
1. Failure Analysis (FA): Utilizing advanced instruments such as optical microscopes, scanning electron microscopes (SEM), acoustic microscopes (EMMI), beam-induced resistance change (OBIRCH), and X-ray systems, the company can precisely locate defects and analyze failure mechanisms in chips and electronic components. Services cover multiple aspects including IC circuit repair, engineering sample preparation, fault analysis, and signal testing.
2. Materials Analysis (MA): Equipped with advanced instruments such as Energy Dispersive X-ray Spectrometer (EDX), Dual-Beam Focused Ion Beam (FIB), and Transmission Electron Microscope (TEM), the company possesses capabilities in wafer microstructure and materials analysis. It can characterize the microstructure of semiconductor materials, analyze their composition, and evaluate process quality, providing data support for chip design and optimization of manufacturing processes.
3. Reliability Assurance (RA): Based on international and industry standards (such as AEC-Q series, IEC 17025, etc.), the company offers one-stop reliability verification services including environmental reliability testing, life assessment, and component screening.
III. Service Philosophy and Industry Value
As an independent third-party testing laboratory, JiuXi Testing adheres to the principles of objectivity, fairness, and professionalism. In the context of increasingly specialized semiconductor industry divisions, third-party testing and analysis labs play a crucial role in supporting customer R&D, identifying design or process defects, and improving product yield and performance. Through precise and efficient testing and analysis services, JiuXi Testing helps customers identify potential risks early in the product development stage, ensure consistent quality during mass production, and trace root causes of failures during application phases, establishing itself as an indispensable quality and technical support platform within the semiconductor supply chain.
Looking ahead, JiuXi Testing will continue to deepen its expertise in four strategic areas—automotive electronics, rail transit electronics, low-altitude flight electronics, and AI chips—constantly enhancing technical capabilities and service standards, and supporting the high-quality development of China's semiconductor industry through professional testing and verification services.
