Component shielding

A system comprising:

• a printed circuit board oriented along a first plane, the printed circuit board having a device that extends in a direction away from the first plane and is at least one of capable of producing a radiated signal or is sensitive to a radiated signal produced by another device;
• a component shield having a wall structure and a cover structure, the wall structure oriented perpendicular to the first plane, and the cover structure connected to the wall structure and oriented parallel to the first plane;
• a housing structure oriented along a second plane, the second plane being substantially parallel to the first plane and the first and second planes defining a shielded space within which the component shield and the device reside;
• and
• a shielding layer, the shielding layer:
• disposed in contact with the cover structure of the component shield and with the housing structure;
• configured to attenuate radiated signals;
• oriented along a third plane substantially parallel with the second plane;
• residing in the shielded space;
• and
• having an irregular cross-section along a fourth plane perpendicular to at least one of the first, second, or third planes, the irregular cross-section being at least in a region between the cover structure of the component shield and the housing structure and having a protrusion from the third plane in which the shielding layer is oriented, the protrusion compressed by contact with the housing structure.
