Abstract
An RF shield for use on tightly packed printed circuit boards has a normally-closed lid that can be opened to provide repair access to shielded components and then reclosed. The shield is a five-sided metal can having a top surface (12) with a lid defined on one edge by a fold line (20) and on the other three edges by partial shear lines (22, 24, 26) through the thickness of the metal top surface. The shear lines define frangible connections between the lid and top surface (18) that can be severed to allow the lid to open. The fold line serves as a hinge about which the lid can pivot for opening. Upon closing the lid can be spot-soldered to hold it shut.
