JEDDEC JESD22-A146 Interconnect Fatigue Failure Testing
The JEDEC JESD22-A146 standard specifies a method to evaluate the mechanical reliability of interconnects in semiconductor devices through controlled fatigue testing. This service ensures that the electrical and physical integrity of microchip connections withstand repeated stress cycles, which is critical for ensuring long-term performance and durability.
The testing process involves subjecting the interconnects to cyclic loading until failure occurs or a predetermined number of cycles is reached. The test setup includes specialized equipment designed to simulate real-world conditions that the device might encounter in use. This method helps identify potential weaknesses before the product reaches market, ensuring compliance with international standards and industry best practices.
The JESD22-A146 standard covers a wide range of interconnect types used in semiconductors, including solder joints, wire bonds, and through-silicon vias (TSVs). The testing protocol is designed to replicate the environmental stresses that these connections might face during the lifecycle of the device. This includes temperature cycling, thermal shock, and mechanical vibration.
During the test, specimens are subjected to a sequence of stress cycles that simulate operational conditions. These cycles include temperature changes from extreme cold to hot, mechanical vibrations, and electrical loading. The goal is to identify any defects or weaknesses in the interconnects under these conditions. The testing process typically involves monitoring key parameters such as resistance, capacitance, and dielectric breakdown voltage.
The equipment used for this test includes a fatigue tester capable of precise control over temperature, humidity, vibration, and electrical loading. The tester is equipped with sensors to measure the mechanical and electrical properties of the interconnects during testing. Additionally, non-destructive inspection techniques such as X-ray fluorescence (XRF), scanning electron microscopy (SEM), and focused ion beam (FIB) are used for defect characterization.
The testing process can be customized based on specific requirements. For instance, different stress profiles or cycle counts can be specified to cater to various product lifecycles and operational conditions. The service also provides detailed reports that include not only the test results but also recommendations for improving interconnect reliability.
