Meta patents metal cages to stop electronic parts from interfering with each other
Meta describes a method for building electronic devices where specific radio-frequency parts are wrapped in a metal shield. This shield is partly built into the circuit board to stop these parts from sending out signals that mess up other nearby components.
In the filing’s own words
A device of the subject technology includes a radiofrequency (RF) circuit enclosed within a shielding and an RF cage partially enclosing components of the RF circuit. The RF cage is configured to protect RF components of the RF circuit against an electromagnetic interference (EMI) caused by the components. The RF cage is partially embedded within a printed circuit board (PCB), and the RF circuit is mounted on the PCB via a number of ball grid arrays (BGAs).
What exactly they claim (claim 1)
1. A device, comprising: a radiofrequency (RF) circuit enclosed within a shielding; and an RF cage partially enclosing a plurality of components of the RF circuit and configured to protect RF components of the RF circuit against an electromagnetic interference (EMI) caused by the plurality of components, wherein: the RF cage is partially embedded within a printed circuit board (PCB); and the RF circuit is mounted on the PCB via a plurality of ball grid arrays (BGAs).
