Abstract
A method of forming an opening or cavity in a substrate, for receiving an electronic component, consists of or includes providing a patterned opaque masking layer on or adjacent a first major surface of the substrate, the masking layer having an opening overlying the position where the cavity is to be made, removing material from the substrate by laser ablation through the opening thereby forming an opening or cavity of a suitable size for receiving said electronic component.
