    摘要: A shielding structure is provided for shielding a signal path extending between a first layer and a second layer in an electronic device at a transition region with a transition that extends in a first direction and a second direction orthogonal to the first direction. The shielding structure includes a shielding structure portion, which includes a first shielding via in proximity to a first area of the signal path at the transition; a second shielding via in proximity to a second area of the signal path at the transition; and an area metallization electrically coupled to the first shielding via.

    摘要: A method for mini module EMI shielding effectiveness evaluation comprises providing a test vehicle including at least one test platform. The test platform includes at least one mini emitter, a mini receiver with a reference shield, and a mini receiver with a shield under test. EMI shielding effectiveness transmission signals are applied to the at least one mini emitter. Signals received by the mini receiver with a shield under test and the mini receiver with the reference shield are evaluated. The mini emitter, mini receiver with the reference shield, and mini receiver with the shield under test comprise components fabricated concurrently and under fabrication conditions used for fabrication of the test platform of the test vehicle. As used herein, a mini emitter and mini receiver may be interchanged according to the requirements of a given EMI shielding effectiveness evaluation.
