Shield and electronic assembly

Abstract

The present disclosure provides a shield and an electronic assembly. The electronic assembly comprises a base plate and a chip located on the base plate. According to the embodiments of the present disclosure, the shield is plate-shaped; in the shield, a first cover cap is connected to side walls around a second cover cap, the first cover cap is used for electromagnetic shielding around the chip, electromagnetic radiation is refracted multiple times on an inner surface of the first cover cap, energy of the electromagnetic radiation is lost during the refraction process, radiation energy of the electromagnetic radiation coupled to the first cover cap is reduced, and radiation energy radiated out of the first cover cap is reduced, such that an electromagnetic shielding effect of the shield is good; in addition, the second cover cap is closer to the chip than the first cover cap, and the second cover cap and the chip absorb heat generated by the chip; and because the first cover cap is connected to the second cover cap, the first cover cap can also absorb energy in the chip. In conclusion, the shield achieves not only the effect of heat radiation but also the effect of electromagnetic shielding, and is thus beneficial to reduce costs.
