Research checked: 2026-10-15- Purpose
- Potential engineering use: [Latent opens in stacked organic-substrate microvias] Correlate reflow-induced resistance changes with microvia cross-sections. [Board-level BGA thermal fatigue] Compare solder fatigue and reinforcement under passive thermal cycling.
- Technical approach
- Detailed mechanism and process conditions are not documented here. Confirm with the supplier.
- Scope of use
- Potential engineering use: [Latent opens in stacked organic-substrate microvias] Correlate reflow-induced resistance changes with microvia cross-sections. [Board-level BGA thermal fatigue] Compare solder fatigue and reinforcement under passive thermal cycling.
- Limitations and open questions
- [Latent opens in stacked organic-substrate microvias] Localize intermittent opens; generic sections or device tests do not establish microvia life. [Board-level BGA thermal fatigue] Require board-level specimens, monitoring and localization; component testing is not automatically board-level validation. Supplier confirmation of samples, specifications and service availability is required; improvement has not been demonstrated.
- Public evidence
- The official source lists PCB thermal cycling with resistance monitoring.
