Abstract
A printing plate for use in fabricating electronic circuitry on a substrate. It comprises a body layer (12), and a non-metallic pattern definition layer (14) over the body layer having a printing pattern anisotropically etched into its outer surface. The material of the body layer (12) may be selected to have thermal expansion properties which substantially match those of the substrate, whilst the pattern definition layer may be selected for its etching characteristics.
