**Citable summary**: Samsung Electro-Mechanics's confirmed suppliers/cost counterparties include Ajinomoto, 코스모신소재 plus 2 undisclosed/aggregate relationships. Per the valuechain.wiki graph: 4 cost edges, backed by 4 dated sources, 2 of them primary filings (as of 2026-07-12).

### Ajinomoto (mid)  → /ajinomoto.md
- note: Sources interlayer dielectric near-solely from Ajinomoto ABF — however well it makes FC-BGA, it cannot without ABF supply, an essential upstream dependence.
