Methods and apparatus for mounting an electromagnetic interference shielding cage to a circuit board
First Claim
1. A circuit board assembly comprising:
- a circuit board defining a first surface, a second surface opposing the first surface, a boundary, and a slot along a portion of the boundary, the slot configured to receive a transceiver module; and
a module cage coupled to the circuit board, the module cage positioned within the slot defined by the circuit board and surrounding at least a portion of the transceiver module, the module cage having a first housing portion extending past the first surface of the circuit board and a second housing portion extending past the second surface of the circuit board, the module cage configured to provide electromagnetic interference shielding for the transceiver module.

Abstract
An EMI shield, or module cage, mounts to a circuit board such that a first portion of the module cage extends above a first planar surface of the circuit board and a second portion of the module cage extends below a second planar surface of the circuit board. The module cage surrounds a corresponding transceiver module and allows airflow to travel across the transceiver module and through the module cage in a direction substantially perpendicular to a planar surface of the circuit board to cool the transceiver module. In one arrangement, multiple module cages attach to the circuit board in a modular configuration. Such a configuration allows attachment, to the circuit board, of the number of module cages corresponding to the number of transceiver modules required or utilized by the circuit board.
