IEC 61587-3 Environmental Radiation Testing of Electronic Modules
The IEC (International Electrotechnical Commission) Standard 61587-3 provides a framework for the environmental testing of electronic modules exposed to ionizing radiation. This standard is crucial in ensuring that electronic devices and semiconductor components can withstand the harsh conditions encountered in space, aerospace, nuclear power plants, and other high-radiation environments.
The standard focuses on the effects of gamma rays (e.g., Co-60), X-rays (e.g., 1 MeV), and electron beams. It aims to simulate the radiation environment that electronic modules might encounter during their operational life. By subjecting the components to controlled levels of ionizing radiation, we can evaluate their performance degradation and reliability.
Testing according to IEC 61587-3 is essential for compliance with international regulations governing products intended for use in high-radiation environments. The standard requires that electronic modules undergo a series of tests to ensure they meet specific acceptance criteria. This includes measuring the current, voltage, and power consumption changes due to radiation exposure.
The testing process involves placing the electronic module into a specially designed chamber where controlled levels of ionizing radiation are introduced. The specimen must be thoroughly prepared before testing; this typically involves cleaning the surface of the module, ensuring all connectors and interfaces are secure, and applying any necessary protective coatings if specified by the standard.
Once the module is prepared, it undergoes exposure to various types of radiation at different intensities and durations. Afterward, detailed measurements are taken to assess changes in electrical characteristics such as resistance, capacitance, and inductance. Additionally, functional tests may be conducted to check for any failures or performance issues resulting from the radiation.
The results from these tests provide critical insights into how well the electronic module will perform under real-world conditions. This information is invaluable for quality managers, compliance officers, R&D engineers, and procurement teams who need assurance that their products meet stringent safety and operational requirements.
