ASTM F1882 Single Event Effect (SEE) Testing of Microelectronics
The ASTM F1882 standard is a crucial tool in the aerospace and defense sectors, where microelectronic components are subjected to extreme environments such as space radiation. This testing ensures that these critical components can withstand the harsh conditions encountered during missions outside Earth's protective magnetosphere.
ASTM F1882 specifies procedures for simulating single event effects (SEE) on microelectronics. These effects, including ionizing radiation and high-energy particles, can cause temporary or permanent malfunctions in electronic circuits. The test aims to predict the performance of microelectronic devices under expected SEE conditions, thereby enhancing mission reliability.
Single Event Effects are divided into two primary categories: Single Event Latchup (SEL) and Single Event Upset (SEU). SEL occurs when a particle strikes a transistor in such a way that it causes an unintended flow of current. SEU results in the temporary alteration of data stored in a memory cell without causing permanent damage to the device.
The ASTM F1882 SEE test involves exposing microelectronic components to a controlled environment simulating the high-energy particle radiation found in space. This includes protons, electrons, and heavy ions. The testing apparatus typically consists of Van de Graaff generators or linear accelerators capable of producing the necessary particle energies.
Specimen preparation for ASTM F1882 involves selecting representative components based on their intended use. These components are then mounted onto a test board that provides necessary electrical connections and interfaces with the test equipment. The test setup ensures that the device under test (DUT) is exposed to the particle flux in a manner consistent with its operational environment.
The ASTM F1882 standard specifies acceptance criteria based on the failure rate of the DUTs after exposure to SEE conditions. Typically, the allowable failure rate is set at 10^-7 per hour for commercial applications and as low as 10^-9 per hour for critical military and space systems.
The testing process involves exposing the specimen to a series of particle strikes while monitoring electrical parameters such as voltage and current. The test is conducted in a controlled environment that maintains precise temperature, humidity, and pressure conditions to replicate real-world operational settings.
Results from ASTM F1882 SEE testing are reported based on the observed effects on the DUTs. These reports include details of any malfunctions or failures detected during the test, along with recommendations for design modifications if necessary. The data provides valuable insights into the robustness of microelectronic components and helps in making informed decisions regarding component selection and system design.
The ASTM F1882 standard is widely recognized within the aerospace and defense industries as a key tool for ensuring mission success by mitigating risks associated with SEE events. By adhering to this standard, manufacturers can enhance the reliability of their products, thereby reducing potential mission disruptions and costly failures in space missions.
Understanding the ASTM F1882 SEE testing is essential for quality managers, compliance officers, and R&D engineers who are responsible for ensuring that critical components meet stringent performance requirements. This knowledge also benefits procurement teams looking to source high-quality microelectronic devices for their projects.
Applied Standards
The ASTM F1882 SEE testing protocol is based on the International Organization for Standardization (ISO) and American Society for Testing and Materials (ASTM) standards. This ensures that the testing methods are internationally recognized and widely accepted within the aerospace and defense industries.
