Abstract: A shield for shielding a portion of an electronic component from undesirable emissions from neighboring components. The shield comprises a metal body configured to be attached to a substrate, and solder selectively applied to a lower portion of the metal body in manner that allows for both location and volume of the solder to be controlled. A bond is created between the solder and the metal body. The bond may be a metallurgical bond created by proximity of the solder to the at least one leg and sufficient heat and time to bring the solder to a melting temperature of the solder; or a diffusion bond created by heat and pressure. A method of attaching the shield to the substrate is also described.
