Lot Acceptance Testing provides screening and qualification tests to enable the use of Ohmcraft’s standard parts in flight applications (Aerospace/Space). Ohmcraft can screen and qualify its resistor products to MIL-PRF-55342, MIL-PRF-49462, NASA EEE-INST-002 (Level 1 or Level 2) or a custom test plan. LAT Testing includes but is not limited to:
