Product Description:
Lamination & Material Selection
| Focus Area | Specific Requirements |
|---|---|
| Substrate | High-Tg FR-4 (Tg ≥ 150°C, 170°C recommended), low moisture absorption, good heat resistance |
| Copper Foil Thickness | Signal layer: 0.5oz ~ 1oz; Power/GND layer: 1oz ~ 2oz; High-current paths: ≥ 2oz |
| Lamination Symmetry | Multilayer stack-up must be symmetrical to prevent board warpage |
