Abstract

See full text

A method for forming passive electrical devices that includes depositing a photo reactive layer over a sidewall of a via that extends through a printed circuit board; inserting a light pipe having a mask configured to provide a passive electronic device geometry within the via to an entire depth of the via; and exposing the photo reactive layer to radiation provided by the light pipe to provide a pattern having the passive electronic device geometry on the sidewall of the via.
