Printed circuit board
A printed circuit board includes a first insulating layer, an embedded pattern embedded in one surface of the first insulating layer, a pad formed on the one surface of the first insulating layer, and a post, wherein the center of a side surface of the post is in contact with the one surface of the first insulating layer.
1. A printed circuit board comprising:
a first insulating layer;
an embedded pattern embedded in one surface of the first insulating layer;
a pad formed on the one surface of the first insulating layer; and
a post, wherein the center of a side surface of the post is in contact with the one surface of the first insulating layer.
2. The printed circuit board of claim 1 , wherein a bottom part of the post is embedded under the one surface of the first insulating layer and an upper part protrudes from the one surface of the first insulating layer.
3. The printed circuit board of claim 2 , wherein the post further comprises an intermediate layer interposed between an upper part of the post and a lower part of the post.
4. The printed circuit board of claim 3 , wherein a lower surface of the intermediate layer is placed on a same plane as the one surface of the first insulating layer.
5. The printed circuit board of claim 3 , further comprising a bottom layer interposed between the pad and the one surface of the first insulating layer.
6. The printed circuit board of claim 5 , wherein the bottom layer and the intermediate layer are formed in a same layer.
7. The printed circuit board of claim 1 , further comprising a second insulating layer formed on the first insulating layer and comprising a through hole,
wherein the embedded pattern and the pad are exposed through the through hole.
8. The printed circuit board of claim 7 , wherein the printed circuit board comprises pads and wherein the embedded pattern is arranged between the pads.
9. The printed circuit board of claim 7 , wherein the second insulating layer is a solder resist layer and an opening is formed in the solder resist layer to expose the post.
10. The printed circuit board of claim 7 , wherein the printed circuit board comprises posts and the through hole is arranged between the posts.
11. A printed circuit board comprising:
a first insulating layer comprising an upper surface;
an embedded pattern embedded in the first insulating layer extending from the upper surface into the first insulating layer;
a pad disposed on the upper surface of the first insulating layer spaced apart from the embedded pattern; and
a post,
wherein a center of a side surface of the post is in contact with the upper surface of the first insulating layer.
12. A printed circuit board comprising:
a first insulating layer;
an embedded pattern embedded in the first insulating layer extending from one surface of the first insulating layer into the first insulating layer;
a pad disposed on the one surface of the first insulating layer; and
a post protruding from the one surface of the first insulating layer,
wherein the post extends into the first insulating layer less than a thickness of the first insulating layer, and
wherein the post protrudes from the one surface by the same distance as the post extends into the first insulating layer from the first surface.
