Description of the invention (3) His specific or unspecified shape, except for one or both sides of the circuit board 1 on either side of the sinking hole 2 or the side of the polygonal side hole The electronic component of the hole 2 is provided with a plurality of circuit contacts 3, thereby forming a circuit board having a sinking hole, and one or more electronic components are disposed in the sinking hole 2 4 (for example, an electrical circuit such as an IC transistor, an electrical connector, a resistor, a capacitor, or other circuit board), and the pin 4 1 of the electronic component 4 is soldered or otherwise contacted with the circuit contact 3. However, in the case of using a multi-layer printed circuit board, as shown in the third and fourth figures, the sinking hole 2 is implemented as a class hole shape, and one or more of the class faces 2 1 are selected to have a circuit. The contact 3 forms a circuit board in which a plurality of electronic components 4 can be stacked in the sinking hole 2. Secondly, the sinking hole 2 described in the present application is not limited to being implemented as a penetrating shape. As shown in FIG. 5, the selected circuit board 1 may be provided with one or more recessed holes on one or both sides thereof. The hole 2' is disposed, and the circuit contact 3 is disposed on the bottom surface of the hole or the side of the hole or the side of the edge of the edge of the hole 2, thereby forming a circuit board having a sink hole. And providing one or more electronic components 4 by means of the recessed holes 2'. Similarly, the embodiment of the recessed hole 2' can be a multi-layer printed circuit board, and one or more of the one-sided or two-sided recessed ones are selected. The hole 2' (as shown in the sixth figure) and the one or more layers of the level surface 21 are provided with the circuit contacts 3, thereby forming a plurality of electronic components that can be stacked in the sinking hole 2 4 circuit board. In addition, the person specified in the creation of the sinking hole 2, 2 ’
