For example, the shield can assembly may be soldered to the PCB 300 through an SMD (surface mounted device) process. In one or more embodiments, the shield can assembly 390 may cover at least one electrical component 351 disposed on the PCB 300. For example, the shield can assembly 390 may block electromagnetic waves generated by the covered electrical component 351. In one or more embodiments, the shield can assembly 390 may form a shield area S on the PCB 300. In one or more embodiments, the shield can assembly 390 may block the transmission of electromagnetic waves between the inside and outside of the shield area S by covering the at least one electrical component 351 positioned on the shield area S and may prevent or mitigate an occurrence of noise between electrical components disposed inside and outside of the shield area S.
Hereinafter, one or more embodiments is described based on the assumption that the shield can assembly 390 is disposed on the first board surface 300A of the PCB 300. However, it shall be noted that the embodiment is for ease of description. For example, unlike drawings, the electrical component 351 and the shield can assembly 390 may be disposed on the second board surface 300B of the PCB 300 and may also be simultaneously disposed on the first board surface 300A and the second board surface 300B.
