Abstract
An EMI-resistant circuit board assembly includes a plurality of circuit boards arranged in a stack and a metal shielding frame respectively sandwiched in between each two adjacent circuit boards. One of the circuit boards has at least one high-speed device producing high-frequency noises to the ambient, which result in EMI effect. The metal shielding frame is electrically connected to the ground potential of the circuit boards and shields the high-speed device on the circuit board to guide the high-frequency noises to the ground potential.
Claims10
An EMI-resistant circuit board assembly comprising:
- at least two circuit boards arranged in a stack and provided respectively with an electronic circuit thereon, the circuit boards including a first circuit board having at least one high-speed device that produces high-frequency noises;
- and
- a shielding frame made of conductive metal material, sandwiched between each two of the circuit boards and electrically connected to a ground potential of the circuit boards;
- wherein the shielding frame shields the at least one high-speed device for guiding the high-frequency noises to the ground potential.
