| 摘要 |
The invention relates to a basic material for making a PWB laminate, which is a foiled UD-prepreg comprising a layer of a conductive metal foil bonded to a layer made up of parallel, unidirectionally oriented reinforcing fibres, having a diameter of below 30 mu m, impregnated with not yet fully consolidated matrix resin. The foiled UD-prepreg can be used to manufacture UD-crossply PWB laminates by stacking and pressing them together with, in between, other UD-layers, which may be either non-foiled UD-prepreg layers, or non-flowing UD composite layers. |
