PURPOSE: A PCB attached an SMD of two pins is provided to increase the circuit density of the PCB by perpendicularly and downwardly inserting the SMD into the PCB. CONSTITUTION: The PCB(100) on which an SMD having the type of two pins has a hole. A pad(106) is mounted on the front and rear surfaces to surround the hole. A SMD(102) having the type of two pins is mounted on the PCB(100). The SMD(102) is perpendicularly and downwardly inserted into the PCB(100) when the SMD(102) is mounted on the PCB(100). After inserting the SMD(102) into the PCB(100), the SMD is soldered by brazing. The SMD(102) includes a passive device such as a resistor, a capacitor, inductor, etc.
