ABSTRACT:
The invention relates to Electromagnetic Interference ("EMI") shielding of electrical components mounted on circuit boards. An EMI shielded assembly is provided, comprising a circuit board having at least one electrical contact distributed around the perimeter of an area within which EMI shielding is desired, an EMI shielding cover encircling the area over the contact and covering the area, and a ring-like EMI shielding gasket encircling the area and compressed between the contact and the cover, the gasket in an uncompressed state having low portions alternated with high portions spaced around the gasket. The high portions are spaced away from the at least one electrical contact above the low portions, and the high portions are displaceable toward the low portions upon compression of the gasket. A method for EMI shielding is also provided.
