| 摘要 |
A circuit board assembly is configured to attenuate and prevent electro-magnetic fields from interfering with operation below a desired cutoff frequency, of electro-magnetic interference (EMI) susceptible circuit board electronics disposed within a shielded enclosure, while allowing signals to be transmitted between the EMI susceptible circuit board electronics at frequencies below the desired cutoff frequency, and circuits or devices external to the shielded enclosure.
