    Abstract: A laminate, adapted to be used as a supporting board for a printed circuit, is disclosed which comprises layers of an electrically non-conductive matrix material reinforced with unidirectionally (UD) oriented fibers with the layers comprising individual matrix material having different directions of orientation. The layers are stacked to form a laminate of crossing layers, and the laminate has a core plane relative to which the crossing layers are in mirror image relationship so that the laminate has orthotropic properties. The laminate comprises layers of adhesive material present at least between any pair of layers of UD-reinforced matrix material having different directions of orientation.
