The Innovative Research of Integrating Electromagnetic Shield into Three-Dimensional Circuit

The word "innovative" in title is the new thought to measure the electromagnetic shielding capability level of circuit. Circuits were classified into non-shielding circuits, semi-shielding circuits and shielding circuits. What\´s more, a circuit was really produced and was tested in different shielding levels, and the result was analyzed. It was obvious, and proved that it was important to design the structure and configuration of the electromagnetic shield for delicate circuit, to design the three-dimensional configuration of circuit, to emplace three-dimensional positions of circuit components, to tightly pack circuit with electromagnetic shield. And nowadays, the electromagnetic circumstances are becoming more and more complicated. Hence the application of shielding circuit plays a significant role in the stability improvement of the circuit, especially of the highly subtle circuit
