Abstract
A multilayer circuit board having a conformal layer of an insulating material separating a circuit core from an adjacent insulating layer is disclosed. The conformal layer encapsulates the substrate and conductive pattern of circuit lines in the circuit core, thereby reducing failures caused by impurities trapped during lamination. The multilayer circuit board is manufactured by coating at least one circuit core with the conformal layer of insulating material before final lamination of the circuit cores into a multilayer circuit board.
