Pick the Laminate That Closes the Link
Material choice on a high-speed board is a loss budget, not a brand. Tell us the interface and the channel reach, and this picks the laminate class that typically closes the link at the lowest cost.
- 01High-Tg FR-4 — lowest material cost
- 02Mid-loss laminate
- 03Low-loss (Megtron-class)
- 04Ultra-low-loss laminate

Guidance is based on typical insertion-loss budgets for each interface and representative laminate Dk/Df ranges from manufacturer datasheets. The right grade for your board depends on exact length, layer count, and connector loss — we confirm it by modelling the channel during DFM. Megtron is a Panasonic product family; equivalent low-loss grades from other makers apply.
