Abstract

A printed circuit board comprises a board main body, a sensor, an external connection pad, and a hollow-structured electrical conductor. The board main body has a top face and a bottom face opposite the top face. The sensor is mounted on one of the top face and the bottom face of the board main body. The external connection pad is provided on the top face or the bottom face of the board main body opposite the sensor. The hollow-structured electrical conductor extends through the board main body and electrically connects the sensor to the external connection pad.

First claim

What is claimed is:

1 . A printed circuit board, comprising:
a board main body having a top face and a bottom face opposite the top face;
a sensor mounted on one of the top face and the bottom face of the board main body;
an external connection pad provided on the top face or the bottom face of the board main body opposite the sensor; and
a hollow-structured electrical conductor extending through the board main body and electrically connecting the sensor to the external connection pad.

2 . The printed circuit board of claim 1 , further comprising a plurality of hollow-structured electrical conductors extending through the board main body.

3 . The printed circuit board of claim 2 , further comprising a plurality of external connection pads, one external connection pad is provided for each of the hollow-structured electrical conductors.

4 . The printed circuit board of claim 3 , wherein the plurality of external connection pads are electrically independent.

5 . The printed circuit board of claim 2 , wherein the plurality of hollow-structured electrical conductors are formed along a peripheral edge of the board main body.

6 . The printed circuit board of claim 5 , wherein the board main body has a shape with four corners and the plurality of hollow-structured electrical conductors are formed at or near the four corners of the board main body.

7 . The printed circuit board of claim 1 , wherein the board main body has a flat suction face formed over a predetermined area on the one of the top face and the bottom face of the board main body on which the external connection pad is disposed.

8 . The printed circuit board of claim 1 , wherein the board main body includes a locating region corresponding to an external locating guide.

9 . The printed circuit board of claim 1 , wherein the board main body has an asymmetrical shape with a chamfer at one of a plurality of corners of the board main body.

10 . The printed circuit board of claim 3 , further comprising a plurality of connection terminals electrically connected to the plurality of hollow-structured electrical conductors and the plurality of external connection pads.

11 . The printed circuit board of claim 10 , wherein the plurality of connection terminals are press-fitted into the plurality of hollow-structured electrical conductors.

12 . The printed circuit board of claim 11 , wherein the board main body has a shape with four corners defining a first side and an opposite second side.

13 . The printed circuit board of claim 12 , wherein a first pair of the plurality of hollow-structured electrical conductors are aligned along the first side and spaced apart by a first interval and a second pair of the plurality of hollow-structured electrical conductors are aligned along the second side and spaced apart by a second interval.

14 . The printed circuit board of claim 13 , wherein the first interval is equal to the second interval.

15 . The printed circuit board of claim 14 , wherein a first connection terminal connected to one of the first pair of the plurality of hollow-structured electrical conductors extends straight in a planar direction and a second connection terminal connected to one of the second pair of the plurality of hollow-structured electrical conductors extends in an L-shape.

16 . The printed circuit board of claim 13 , wherein the first interval is greater than the second interval.

17 . The printed circuit board of claim 16 , wherein the plurality of connection terminals each extend straight in a planar direction to the first pair of the plurality of hollow-structured electrical conductors and the second pair of the plurality of hollow-structured electrical conductors.
