Abstract
A method for shielding one or more circuits () of a printed circuit board includes depositing a layer of dielectric material () over a printed circuit board substrate () and the printed circuits (), creating a trench-like opening () in the dielectric layer () such that the trench-like opening () surrounds the one or more circuits () to be shielded, depositing a layer of metal () over the layer of dielectric material () and within the trench-like openings (), creating a solder pad () at each location where an electrical connection is to be made to the printed circuits () by removing a border of the metal layer () surrounding each connection location, and providing a microvia () through each solder pad () penetrating the dielectric layer () and terminating at the metal of the printed circuit ().
