Abstract

A structure for stacking Printed Board Assemblies (PBAs) in an electronic device is provided. The structure for stacking PBAs in an electronic device includes a clip mounted on a main Printed Circuit Board (PCB), a sub-PCB including a ground portion, a sub-PBA including the sub-PCB, and a clip header mounted on a lower part of the sub-PBA, wherein the clip header is inserted into the clip. Therefore, electronic components mounted on a main PCB can be shielded from outer electromagnetic waves while reducing material costs without using a shield can, and a sub-PBA can be stacked on the main PBA.

Claims

1. A structure for stacking Printed Board Assemblies (PBAs) in an electronic device, the structure comprising:

a clip mounted on a main Printed Circuit Board (PCB);

a sub-PCB comprising a ground portion;

a sub-PBA comprising the sub-PCB; and

a clip header mounted on a lower part of the sub-PBA,

wherein the clip header is inserted into the clip.

2. The structure of claim 1, further comprising a main PBA comprising the clip.

3. The structure of claim 1, wherein the ground portion is connected to the clip header.

4. The structure of claim 1, wherein the clip header comprises a structure mounted on the sub-PCB and protruded toward the main PCB.

5. The structure of claim 4, wherein the clip header comprises:

a mounting portion coupled to the sub-PCB and having contact with the edge of the ground portion; and

a wall protruded from the mounting portion and fastened to the clip.

6. The structure of claim 1, wherein the clip comprises a protruded portion connected to the ground portion of the main PCB for forming insertion space for housing the clip header, and for fixing the clip header with an elastic restoring force.

7. A structure for stacking Printed Board Assemblies (PBAs) in an electronic device, the structure comprising:

a main PBA comprising a clip mounted on a main Printed Circuit Board (PCB);

a sub-PCB comprising a ground portion connected to a clip header; and

a sub-PBA comprising the sub-PCB,

wherein the clip header is mounted on a lower part of the sub-PBA and inserted into the clip.

8. The structure of claim 7, wherein the clip header comprises a structure mounted on the sub-PCB and protruded toward the main PCB.

9. The structure of claim 8, wherein the clip header comprises:

a mounting portion coupled to the sub-PCB and having contact with the edge of the ground portion; and

a wall protruded from the mounting portion and fastened to the clip.

10. The structure of claim 9, wherein the clip comprises metal.

11. The structure of claim 7, wherein the clip comprises a protruded portion connected to the ground portion of the main PCB for forming insertion space for housing the clip header, and for fixing the clip header with an elastic restoring force.
