GH-200 (Type D)
Thin Prepreg with Superior Surface Smoothness
Product form
| Prepreg | GH-200 (Type D) |
Applications
- Semiconductor packages. (FC-CSP, PoP, SiP)
- Thinner Module PWB
Features
- GH-200 (TYPE-D) have hybrid properties of package and high speed materials.
- Good for impedance control as thickness variation is small after press.
- Halogen free material with low CTE values in X, Y directions (α1, α2).
- Good dielectric properties by applying low dielectric glass cloths.
