Material Requirements

The materials used in electronic components must be carefully selected to ensure that they can withstand the harsh conditions of space. This includes ensuring that materials have a low outgassing rate, which can cause contamination of sensitive optical and electronic systems. Components must also be designed to minimize the risk of corrosion and degradation over time. The materials requirements of the ESCC 3402 standard are focused on ensuring that electronic components used in space applications are made of materials that can withstand the harsh conditions of space and are highly reliable. The materials used must be carefully selected based on their physical, chemical, and mechanical properties, and their ability to withstand radiation, temperature extremes, and vacuum. The materials must have a low outgassing rate to minimize contamination in the spacecraft's environment and must not release volatile organic compounds (VOCs) that could damage other components. The materials used must also have a low risk of corrosion and degradation over time, as well as high resistance to mechanical stress, vibration, and shock. Special coatings or materials may be required to protect against radiation and ensure the reliability of the component over the lifetime of the mission. The use of commercial off-the-shelf (COTS) components is allowed, but they must be qualified to meet the materials requirements of the standard.

Manufacturing Requirements

The ESCC 3402 standard defines a set of manufacturing requirements that must be followed to ensure that electronic components are produced to a high standard of quality. This includes requirements for process control, cleanliness, and inspection. Components must be manufactured in a controlled environment to minimize the risk of contamination and to ensure consistency in the manufacturing process. The manufacturing requirements of the ESCC 3402 standard are focused on ensuring that electronic components used in space applications are produced to the highest standards of quality, consistency, and cleanliness. The manufacturing process must be carried out in a controlled environment to minimize the risk of contamination and ensure consistent performance of the components. The manufacturing process must be documented, and process controls must be in place to ensure that components are produced to the required standards. The cleanliness requirements are particularly important for electronic components, and manufacturers must take steps to minimize the risk of contamination from dust, particles, and other sources. The use of cleanrooms, specialized equipment, and cleaning processes may be required to meet the cleanliness requirements of the standard. The manufacturing process must also include inspection and testing activities to ensure that components meet the required specifications and performance criteria. Traceability is critical, and manufacturers must maintain detailed records of the materials, processes, and testing activities used to produce each component.

Testing Requirements

Electronic components must be thoroughly tested to ensure that they meet the requirements of the ESCC 3402 standard. This includes a range of tests to assess the performance and reliability of components under simulated space conditions. Components must be tested to ensure that they can withstand temperature extremes, radiation, and vacuum, as well as other environmental factors such as vibration and shock. The testing requirements of the ESCC 3402 standard are focused on ensuring that electronic components used in space applications are tested rigorously under simulated space conditions to assess their reliability and performance. The testing activities include a range of tests, including thermal cycling, radiation testing, vacuum testing, vibration testing, and electrical performance testing. These tests are designed to simulate the extreme conditions of space and identify any potential failure modes. The testing must be carried out using calibrated equipment and validated test methods, and the results must be documented and analyzed to identify any potential issues or risks. The testing must also include a range of qualification and acceptance tests to ensure that components meet the required specifications and performance criteria. This includes environmental stress screening (ESS) to identify any potential defects in the components that may not be detected during normal testing.

Documentation Requirements

The ESCC 3402 standard requires that a detailed set of documentation be provided for electronic components. This includes documentation on the design, materials, manufacturing, testing, and qualification of components. This documentation must be provided to the customer along with the components and must be kept up to date throughout the lifetime of the component. The documentation requirements of the ESCC 3402 standard are focused on ensuring that the development, manufacturing, testing, and use of electronic components used in space applications are documented and traceable.
