Abstract
A multi-layer circuit board comprises a liquid crystalline polymer bond ply disposed between two circuit layers wherein the liquid crystalline polymer bond ply is formed by treating a film comprising a liquid crystalline polymer with an amount of heat and pressure effective to produce a liquid crystalline polymer bond ply with an in-plane coefficient of thermal expansion (CTE) of 0 to about 50 ppm/° C. and further wherein the multi-layer circuit is formed by lamination at a temperature of 0° C. to about 10° C. less than the melt temperature of the liquid crystalline polymer.
