Pin puller tests are crucial to verify the functionality and reliability of the deployment mechanisms in the CubeSat structure to ensure that the pin pullers perform as expected.

This test ensures that all parts fit together correctly and that there are no issues with mechanical integration. It's an essential step to verify that the design and manufacturing of the components are accurate and that the assembly process will proceed smoothly. 

This test ensures that the CubeSat's mass is within the specified limits and that the mass distribution is as expected. 

The Vibration Test assesses the CubeSat's ability to withstand the mechanical stresses and vibrations it will encounter during launch. This test ensures that all components and assemblies can endure the launch environment without failure or performance degradation
