VIALAM MV 4000 Series - RRCC
Vialam MV 4000 is a high Tg halogen free, glass reinforced resin coated copper foil. The product can be used to replace the standard copper and prepreg construction for IC Substrate. Applications include desktops, notebooks, handheld devices etc. As in MV 2000, it has the advantage that the copper and prepreg are built as one entity thus simplifying the laying up process at customer's end. MV 4000 has also been proven with good decomposition temperature results and is therefore thermally a very stable product to use.
General Features and Benefits
- High Tg resin system
- Ultrathin glass styles
- Low water absorption
- High peel strength

Material Availability
MV 4000 is available in different copper thicknesses, namely, 12 µm, 18 µm, 3/35 µm, 5/35 µm. Copper foils used are according to the IPC 4562 Grade 3 standard. The ultrathin copper foils are also equipped with VLP (very low profile) and HTE (high temperature elongation) properties.
Standard Cu thickness:
| Thickness | Weight | IPC Code |
|---|---|---|
| 12 μm | 1/3 oz | T |
