MTT

Printed circuit boards and their assemblies (PCB & PCBA) are the core components of electronic products, and their reliability directly determines the overall reliability of electronic products. To ensure and enhance the quality and reliability of electronic products, it is essential to carry out comprehensive physical and chemical analyses of failures, identify the underlying failure mechanisms, and then propose corresponding improvement measures. MTT possesses profound technical expertise in board-level failure analysis, a complete range of analytical methods, a vast database of case studies, and a team of experienced experts, providing you with high-quality and efficient failure analysis services.

The purpose of electronic component failure analysis is to employ a variety of testing and analytical techniques and procedures to identify the failure phenomena of electronic components, determine their failure modes and mechanisms, identify the ultimate root cause of failure, and propose recommendations for improvements in design and manufacturing processes. This helps prevent the recurrence of failures and improves the overall reliability of the components.

The continuous rise in complexity and performance requirements of integrated circuits, combined with potential risks across design, manufacturing, packaging, and application stages, has led to frequent occurrences of critical failure modes such as short circuits, open circuits, leakage, burnout, and parameter drift. These issues not only result in costly device scrapping and system downtime but also often trigger disputes over responsibility among designers, foundries, packaging and testing houses, and end-users, causing significant economic losses and reputational risks.

The performance requirements for polymer materials continue to rise, while differences in understanding of high-demand products and processes between customers and suppliers often lead to frequent failures such as fracture, cracking, corrosion, and discoloration. These failures frequently cause disputes over responsibility and result in significant economic losses.

The increasingly harsh service environments of metal components place higher demands on material performance and structural reliability. However, factors such as design flaws, material defects, manufacturing deviations, or improper use can readily trigger typical failures including fatigue fracture, stress corrosion cracking, hydrogen embrittlement, creep, wear, and overload deformation.

Testing of Thermal Management System Components

Thermal management refers to controlling and optimizing heat transfer by coordinating the heat generated by different vehicle components with environmental heat from the perspective of system integration and complete vehicle operation, ensuring each component functions within its most suitable temperature range to enhance overall vehicle performance. The role of thermal management is to maintain various components at optimal operating temperatures through methods such as heat dissipation, heating, and insulation, thereby ensuring automotive functional safety and service life.

Testing of Automotive Electronic Components

As the foundation of vehicle manufacturing, the quality of automotive materials and components is a prerequisite for the success of complete vehicle production. With the continuous enhancement of functions in new vehicle models and the growing demand for ride comfort and safety, automotive manufacturers are required to monitor material quality and safety from the very source.

Automotive Connector Systems

Automotive connectors, as the core of wiring harnesses, are used for the physical connection between harnesses as well as between harnesses and electrical devices, enabling fast switching of electrical signals. They come in a wide variety of forms, and stable, reliable connections along with proper installation and fixation are prerequisites for the dependable transmission of electronic control signals. Under the trend of modern automotive electrification, connector types have expanded and structures have become more complex, serving as a critical guarantee for the reliability of automotive wiring harnesses.

Automotive Reliability Testing

Automotive reliability testing is a comprehensive assessment of a vehicle’s ability to perform specified functions under defined conditions and within a prescribed period of time. It encompasses diverse tests on durability, stability, and environmental adaptability of vehicle systems and components, simulating extreme real-world operating conditions such as high temperatures, severe cold, high humidity, and strong vibrations to verify vehicle performance. By conducting automotive reliability tests, potential failure risks can be detected in advance, guiding design improvements and production process optimization, thereby enhancing overall product quality.

Automotive Component Cleanliness

Automotive component cleanliness testing is the quantitative detection and analysis of residual contaminants on the surfaces and within the interiors of components, particularly key parts such as engines, transmissions, and hydraulic systems. This is directly related to the reliable operation of precision components, ensuring system performance and service life, enhancing overall vehicle quality and durability, and preventing early failures and safety risks caused by contaminants. It is a core element of quality control in modern automotive manufacturing.

Automotive Materials

Automotive material testing is the systematic evaluation of the physical, chemical, and safety properties of materials used in vehicle interior and exterior trims, as well as structural parts. Such testing directly determines vehicle durability, reliability, and occupant safety—such as crash protection and flame retardancy to extend evacuation time—and impacts overall vehicle quality, brand reputation, and market competitiveness. It is an indispensable core process in automotive design and manufacturing.

Green Environmental Protection

Automotive material environmental protection testing is the detection of harmful substances such as volatile organic compounds (VOC) contained in vehicle interior and exterior trim parts and various materials. Heavy metals (such as lead, mercury, cadmium, hexavalent chromium) and other harmful substances are detected. Preventing the volatilization or contact hazards of toxic substances is directly tied to the health of drivers and passengers. It ensures that products comply with increasingly stringent global environmental regulations, such as EU ELV and REACH, helps avoid trade barriers and legal risks, and safeguards the reputation and social responsibility of automotive brands. This is the fundamental guarantee for creating healthy, safe, and compliant automotive products.

CCS Integrated Busbar

The CCS integrated busbar (battery cover plate assembly) integrates the key electrical components of the battery module, such as high-voltage conductive bars, voltage/temperature sampling lines, fuses, and signal transmission channels FPC/PCB, and connectors. It is the core hub for cell energy connection, voltage, temperature, and transmission to the BMS. It is directly related to the reliability of high-voltage connections, the accuracy of sampling data, the effectiveness of fuse protection, and the integrity of the entire BMS signal chain. It forms the fundamental prerequisite for ensuring the safe, stable, and efficient operation of the battery system.
