Failure Assistance for Field Failures in Power Modules
ZESTRON supports manufacturers of power electronics in the technical evaluation of conspicuous failure patterns and the derivation of suitable corrective actions. The aim is to provide a reliable basis for decision-making in quality assurance, delivery capability and communication with module suppliers.
Failure assistance for Power modulesWhen Failures in Power Modules Require Fast Decisions
Field failures, unexplained increases in leakage current, dendrite formation, insufficient humidity robustness or thermally induced damage can immediately call the release, delivery capability or reliability of power modules into question. In such cases, fast and traceable technical evaluation within the specific module design is essential.
ZESTRON assesses relevant influencing factors such as surface, geometry, potting compound, operating conditions and supply chain. This allows possible causes to be narrowed down and concrete next steps to be derived for damage limitation, supplier communication and long-term assurance.
The evaluation is carried out confidentially and in accordance with high information security requirements based on ISO/IEC 27001 and TISAX®.
ApproachFrom the Failure Pattern to a Reliable Basis for Decision-Making
-
Precise Failure Analysis on the Module: ou describe your application case to us, including relevant boundary conditions such as installation situation, operating environment or existing test results. We evaluate the failure pattern with regard to surface, geometry and potting compound and develop reliable hypotheses regarding possible failure causes.
-
Joint Cause Narrowing: We discuss the results directly with your team and, if desired, also together with you and your module supplier. This provides you with a traceable basis for making reliable decisions on the next steps.
-
Deriving Corrective Actions: Based on the evaluation, we coordinate possible corrective actions together with you. The aim is to reach a technically traceable and economically feasible decision in order to prevent recurring failures and ensure the long-term reliability of your systems.
✓ Evaluate the Failure Pattern
✓ Narrow Down Possible Causes
✓ Define Corrective Actions
