Multiple Real Defects Do Not Necessarily Identify the Electrical Failure

What the evidence preview establishes

The available evidence did not isolate a single root cause. Contamination-filled voids influenced some solder fractures, possible wetting or board-finish issues affected some interfaces, and one sectioned device contained a complete die fracture that could itself explain electrical failure.

Why this case matters

Failure analysis must distinguish defect presence from causal proof. When several genuine anomalies coexist, correlate each one with the electrical failure path before selecting the most visually dramatic feature as root cause.
