PCB knowledge: The components of multilayer PCB --- Prepreg
A multilayer board consists of copper foils, thin rigid laminates and prepreg sheets.
Prepreg plays a role of bonding material used for bonding the individual thin laminates of the multilayer boards. It consists of glass cloth impregnated with epoxy resin. Unlike rigid laminates, the epoxy resin is only semi-cured. Epoxy resin is referred to as B-stage when semi-cured.
The prepreg sheets are not sticky. During lamination of the board, the epoxy resin is first changed to a liquid state and later in the press cycle to the fully cured state. During the press cycle, the cured epoxy resin in the thin, rigid laminates softens, but it does not become liquid.
Thicknesses of Prepreg sheets
| Glass Fabric Style | Pressed Thickness | Resin Content | |
| mm | mil | % | |
| 7628H(7630) | 0.213 | 8.4 | 50 |
| 7628(43%) | 0.195 | 7.6 | 43 |
| 7628(41%) | 0.185 | 7.3 | 41 |
| 2116HR | 0.135 | 5.3 | 57 |
| 2116 | 0.12 | 4.7 | 52 |
| 2113 | 0.1 | 4 | 56 |
| 1080 | 0.076 | 3 | 64 |
| 1060 | 0.05 | 2 | 71 |
The pressed thickness varies from one manufacturer to another. As long as the PCB designer does not know the brand(s) of the glass fabrics used by the multilayer board manufacturer, it is more or less impossible to specify a detailed build-up. Therefore, this should be left to the manufacturer.
When a board is required impedance control, the thickness of the dielectric material between the individual layers become important and thickness and tolerance are usually specified by designer.
The minimum thickness of the dielectric material (thin laminate or prepreg sheets) is 75 µm (3 mils) and, in some cases, 100 µm (4 mils).

(This is reference layer stackup. The stackup of multilayer PCB’s can be reached in many different ways.)
