Abstract
A method for the manufacture of a multilayer circuit comprising a liquid crystalline polymer layer, the method comprising treating the multilayer circuit with an amount of heat effective to raise the crystalline to nematic melting point, as defined by the peak endotherm above the glass transition temperature in a differential scanning calorimeter measurement, of the liquid crystalline polymer layer by at least about 10° C.
