Abstract

An electromagnetic interference blocking device is provided for blocking electromagnetic interference between transmission lines formed on a surface of a circuit board. The electromagnetic interference blocking device includes a body configured to be inserted into a slot formed in the surface of the circuit board between the transmission lines, the body including a bottom portion having a comb shape insertable within the slot.

Description

technical field [0001] The invention relates to an electromagnetic interference blocking device and an assembly comprising the same. More particularly, the present invention relates to an electromagnetic interference blocking device for blocking electromagnetic interference in a transmission line formed on a circuit board and an assembly having the device mounted on a circuit board. Background technique [0002] When current flows through a signal line, an electromagnetic field can be generated. The electromagnetic field, in turn, can induce current / voltage in adjacent signal lines, which degrades the performance of the adjacent signal lines. Since the intensity of the induced current / voltage in the adjacent signal line is proportional to the frequency of the current / voltage applied in the signal line, there is hardly any damage due to the induced current / voltage among the signal lines in the DC circuit. resulting performance degradation. However, in circuits using high f...
