Quite simply, the best route to take is to utilise Circuit Board Shielding cans. These comprise a board-mounted 'fence' with a demountable cover or lid. The cover can be supplied with ventilation holes and cable-entry points if required. The fences can be supplied with several standard pin spacings and with or without stand-offs. Using Circuit Board Shielding can considerably reduce radiation and susceptibility problems, thereby making the overall shielding of equipment more cost-effective.
