In general, while electromagnetic waves have useful side effects such as wireless communication and radar, they may adversely affect the operation of electronic devices. This phenomenon is called an electromagnetic interference (EMI) phenomenon. Not only does it generate noise, it also acts as a harmful element to the human body.

Therefore, in recent years, by covering certain electronic components such as semiconductor devices mounted on the printed circuit board inside the electronic device with a shield can, the EMI generated from the electronic components is blocked, so that the electronic devices as well as other electronic devices are prevented.
