JEDEC JESD22-A136 EMC Noise Susceptibility Lifetime Testing
The JEDEC standard JESD22-A136 specifies a method for determining the susceptibility of semiconductor and microchip devices to electromagnetic interference (EMI) in an industrial, scientific, and medical frequency range. This testing is critical for ensuring that electronic components can withstand real-world electromagnetic noise environments without malfunctioning or failing.
The standard involves subjecting the device under test (DUT) to controlled levels of electromagnetic noise over a specified duration. The aim is to simulate the operational environment in which the microchip will be used, thereby identifying any potential weaknesses that could lead to performance degradation or failure. This testing not only ensures product reliability but also helps manufacturers comply with industry and regulatory standards.
The test setup typically includes an anechoic chamber equipped with a controlled electromagnetic field generator capable of generating specific frequency ranges (typically from 1 MHz to 40 GHz). The DUT is placed in the center of this environment, where it is subjected to various types of noise stimuli. The duration can vary depending on the testing requirements but often extends over several days or even weeks.
The process involves meticulous preparation and calibration of both the test equipment and the specimen. This includes ensuring that all external interference sources are minimized to prevent false positives. Specimen preparation may involve encapsulating the DUT in a controlled environment to simulate real-world conditions, which can include varying temperatures, humidity levels, and other environmental factors.
Once the setup is complete, the test begins with the application of noise stimuli across different frequency bands. The intensity and duration of these stimuli are carefully regulated according to the standard's specifications. After each stimulus period, the DUT’s operational status is checked to determine if any degradation has occurred. If issues arise during testing, it allows for early detection and rectification before mass production begins.
Testing under JESD22-A136 can reveal several types of failure modes:
- Signal integrity issues leading to data corruption
- Circuit malfunctions due to interference
- Increased power consumption beyond acceptable limits
- Physical damage or degradation of components over time
The outcome of this testing provides valuable insights into the robustness of semiconductor and microchip designs. It ensures that products perform reliably under adverse electromagnetic conditions, enhancing overall product quality and reducing post-market failures.
| Test Frequency Range | Duration | Type of Stimuli | Environmental Factors Simulated |
