JEDEC JESD22-A148 Electrical Noise Susceptibility Failure Testing
The JESD22-A148 test is a critical procedure used in semiconductor and microchip quality assurance to evaluate the electrical noise susceptibility of devices. This testing ensures that semiconductors can withstand real-world electromagnetic interference (EMI) without failing, thereby enhancing product reliability and performance.
The JESD22-A148 test simulates the effects of high-intensity pulsed electromagnetic fields (PEMFs), which are often encountered in industrial environments. These PEMFs can originate from various sources such as power supplies, motors, transformers, and other electronic devices. By subjecting semiconductors to controlled levels of these fields during this test, engineers can identify potential weaknesses or defects that could lead to failure under operational conditions.
The primary objective of the JESD22-A148 test is to ensure compliance with international standards like IEC 61000-4-3 and EN 55022. Compliance with these standards demonstrates a commitment to product safety, electromagnetic compatibility (EMC), and environmental responsibility. Failure to meet such requirements can result in non-compliance issues, recalls, or even legal action.
During the test, components are exposed to controlled levels of PEMFs that mimic real-world EMI conditions. The intensity of the field is carefully regulated according to specific parameters outlined in the JESD22-A148 standard. This ensures accurate simulation and reliable results. After exposure, the device's functionality is evaluated using industry-standard test methods such as those specified by JEDEC and IEEE. Any deviations from expected behavior indicate a failure, highlighting areas for improvement.
The JESD22-A148 test plays an essential role in the development cycle of semiconductors. It helps manufacturers identify potential issues early on, allowing them to make necessary adjustments before full-scale production begins. This not only improves product quality but also saves time and resources by preventing costly reworks later in the process.
In summary, the JESD22-A148 test is vital for ensuring that semiconductors can operate reliably and safely in environments exposed to high levels of electromagnetic interference. By adhering to this standard, companies demonstrate their commitment to quality assurance and compliance with international regulations.
