Abstract
A cavity is formed in a multilayer substrate at the point of the structure to be trimmed. This enables the embedding of tolerance critical components inside substrates, such as printed circuit boards, modules, and sub-systems. Trimming is done through the cavity using, for example, a laser. After trimming the cavity is easy to fill in with a suitable dielectric material or to cover otherwise, e.g. by using a lid, or to leave the cavity uncovered.
