<p>A multi-layer circuit board (10) comprises a liquid crystalline polymer bond ply (12) disposed between two circuit layers (14, 20) wherein the liquid crystalline polymer bond ply (12) 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 (12) with an in-plane coefficient of thermal expansion (CTE) of 0 to about 50 ppm/°C and further wherein the multi-layer circuit (10) is formed by lamination at a temperature of 0°C to about 10°C less than the melt temperature of the liquid crystalline polymer.</p> |
