Research checked: 2026-10-15- Purpose
- Potential engineering use: [Cooling-stage warpage reversal in large 2.5D FCBGA] Compare material, stack and thermal-history effects on cooling curvature. [RDL film/cure-induced curvature increment] Assess film and cure-material contributions to curvature increments.
- Technical approach
- Detailed mechanism and process conditions are not documented here. Confirm with the supplier.
- Scope of use
- Potential engineering use: [Cooling-stage warpage reversal in large 2.5D FCBGA] Compare material, stack and thermal-history effects on cooling curvature. [RDL film/cure-induced curvature increment] Assess film and cure-material contributions to curvature increments.
- Limitations and open questions
- [Cooling-stage warpage reversal in large 2.5D FCBGA] Require heating/cooling data, cure shrinkage and viscoelastic properties; room-temperature flatness does not establish reversal behavior. [RDL film/cure-induced curvature increment] Require pre/post-film curvature, thickness and properties; indentation modulus is not residual-stress measurement. Supplier confirmation of samples, specifications and service availability is required; improvement has not been demonstrated.
- Public evidence
- The official source lists DMA/TMA packaging-material characterization.
