Test Plan Design for Corrosion Failure Recurrence and Material Selection for a Type of PCB

With analysis of a certain type PCB field failure, it was found that pins of the relay broke because of Kid T-Shirt the CL element corrosion.To verify the above conclusion and choose the better material, the accelerated corrosion test profile was designed.After six cycles, the failure mode was reappeared successfully, which could provide references for the toe ring following work such as material selection and design optimization.
