Dielectric ink, paste and tape compositions having controlled thermal expansion contain a mixture of glasses wherein at least one glass has a coefficient of thermal expansion (CTE) below the CTE of the substrate to which the dielectric composition is applied and at least one glass has a CTE above the CTE of said substrate. The dielectric compositions significantly reduce or eliminate warpage of the substrate.
