Official public page; sample suitability remains unconfirmed.
Research checked: 2026-10-18- Purpose
- Substrate sourcing for GPU, CPU and server flip-chip packages.
- Technical approach
- Fine-line, fine-pitch, high-layer-count substrates connect chips to system circuitry.
- Scope of use
- Substrate sourcing for GPU, CPU and server flip-chip packages.
- Limitations and open questions
- Product availability is documented; no match to the 60 problems is established. Stack-up, temperature-dependent properties and supported design changes are missing. Substrate supply alone does not establish a remedy for warpage reversal, microvia failure or crosstalk.
- Public evidence
- The official FCBGA page lists fine lines, fine pitch, high layer counts and surface finishes.
