Abstract: An electronic device packaging assembly (10) that includes a ball grid array (60) and specialized construction to be able to operate from DC up to 50 GHz with minimal parasitic losses. The packaging assembly (10) includes a thin base plate (14) made of a suitable rigid material. Power vias (48), signal vias (26) and ground vias (46) are formed through the base plate (14) to be coupled to traces, circuit components, and/or the device (12) within the packaging assembly (10). An impedance matching compensation network (28) provides impedance matching between the device (12) and the signal vias (26). The ball grid array (60) includes a plurality of solder balls (68), including ground solder balls (72), signal solder balls (74) and power solder balls (76), electrically coupled to the appropriate via extending through the base plate (14).

Abstract: Apparatus for mounting a circuit board within the chassis of an electronic device are disclosed. The chassis of an electronic device includes a mounting panel assembly having at least one slot for receiving a standoff mounted to the circuit board. Each slot includes a first end suitable for allowing insertion and removal of the standoff through the slot and a second end suitable for engaging the standoff to retain the standoff in the slot for securing the circuit board to the mounting panel assembly. A ramp member extends beneath the slot adjacent to the first end for urging the standoff toward the second end when the standoff is inserted in the slot through the first end.
