EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of AIAA S-112A testing. This standard specifies qualification and quality requirements for electrical components integrated into spacecraft solar panels carrying single-crystal silicon solar cells or gallium arsenide solar cells with any number of ports, including those with metamorphic and reverse metamorphic structures.
In this standard, the term panel describes the assembly of electrical components to be tested. The standard also defines requirements for solar panel manufacturers' quality systems and qualification and characterization of electrical components on solar panels. This standard fully addresses the characteristics of all panel components and panel substrate as they affect only electrical performance. Acceptance test requirements are not defined in this standard.
The qualifier shall obtain or establish drawings and specifications for each of the components and assemblies to be tested and verify, through inspection, that each part to be tested meets the drawing and standard requirements before qualification begins.
If a test fails to qualify due to problems with only a single isolated component or assembly, full qualification may still be achieved with a delta qualification on a similarly manufactured additional coupon containing only an improved version or design of the originally failed component or assembly. A failed component type or assembly type cannot be retested. However, if the component failed due to non-design related workmanship or was otherwise damaged, for example, by use, the condition should be considered non-testing. In such a case, the defective component must be reworked to print.
In the case of a solar cell, the cell can be removed and the circuit skipped as long as the minimum sample amount is maintained. Delta qualification will have the same test configuration, environment, and stress conditions under which the original component or assembly failed. The number of test articles in the delta qualification will be at least the same number as in the original test without failing to pass the qualification.
The purpose of this test is to characterize the parts, materials and processes used in building panels to ensure mechanical and electrical integrity under launch conditions and to characterize the outgassing of components after launch.
If the solar array consists of panel types that contain the same part types but are subject to different mechanical stress or are of different sizes, it is only necessary to determine that the panel type analyzed has the greatest mechanical stress.
