Abstract: A motherboard mounting device (100) includes a standoff (10) and an annular elastic clip (20), both of which are made of electrically conductive material. The standoff includes a head (12), a body (16), and a neck (14) between the head and the body. The clip is undulated, and defines a central opening (22). The clip has a plurality of radial upper and lower ridges (24, 26). The clip is mounted around the neck of the standoff. Several motherboard mounting devices are used to mount a motherboard (50) to a computer enclosure. The heads of the standoffs are extended through the motherboard, and the motherboard is pushed horizontally so it is sandwiched between the heads and the bodies. The motherboard is accordingly securely mounted to the enclosure. The upper ridges and the heads maintain good electrical contact with a grounding trace formed on both upper and lower surfaces of the motherboard.

Abstract: Microstructured materials which can be tuned to a particular range of r.f. frequencies to display particular magnetic permeabilities have been proposed. A typical material is made of an array of capacitive elements e.g. spirals or rolls of conducting material on a non-conducting substrate. These materials can be used as screening material which is effective for the particular band of frequencies to which it is tuned. In one example, the rolls 2 to 5 are orientated normal to the face of the screen 1, which reflects or absorbs the magnetic vector of electromagnetic radiation impinging normal onto the reflector face.
