Lot Acceptance Testing
Lot Acceptance Testing (LAT) is a critical process to ensure the quality and reliability of electronic components and equipment for high-demand industries such as aerospace. Lot Acceptance Testing involves a reduced set of qualification tests to validate specific manufacturing lots before their application, providing full traceability from the manufacturing wafer to the final product.
Our extensive experience in validation and qualification of electronic components (EEE) ensures they adhere to the strictest reliability and performance requirements. With decades of expertise, we cater to the rigorous needs of sectors such as aerospace, defense, and space exploration. By conducting precise testing and maintaining compliance with global standards, we provide assurance in every component, establishing ourselves as a trusted partner for critical missions.
When is Lot Acceptance Testing necessary?
The requirements to determine when Lot Acceptance Testing (LAT), Lot Validation Testing, or Component Qualification are needed are outlined in key standards, including:
- ECSS-Q-ST-60C and ECSS-Q-ST-60-13C for commercial EEE components.
- NASA EEE-INST-002, which provides guidance for electronic parts selection and control in space applications.
- Project-specific documentation.

LAT in the ESA/SCC (now ESCC) System
Within the ESA/SCC (now ESCC) system, Lot Acceptance Tests (now Lot Validation Tests) are specified in Chart V (now Chart F3) of the relevant Generic.
Specification. These specify:
- Tests to be conducted.
- Number of components required.
- Maximum allowable failures.
QCI in the MIL System
In the MIL system, QCI is divided into groups that address various testing aspects:
- Group A and B: Electrical tests (equivalent to LAT3).
- Group C: Endurance subgroup (LAT2 and part of LAT1).
- Group D: Mechanical subgroup (LAT1).
- Group E: Radiation testing.
