Shielding for logic or high frequency circuit

Abstract

Abstract The arrangement provides a screen for logic and high frequency circuits in communication terminal devices, particularly mobile radio devices. A metal cap (1) is provided on the surface of a circuit board (2) where the component or circuitry to be screened are. The back of the metal cap (1) lies on the earthed plane of the circuit board (2) and is connected to it by means of reflow solder around it. For positioning when mounting components on the circuit board (2), lugs (5) are provided on the sides of the metal cap (1) connected to the circuit board (29. These lugs (5) engage in corresponding apertures in the circuit board (2).
