Abstract
A printed circuit board includes a first insulating layer; a pad disposed on the insulating layer and having a protrusion; and a protective layer disposed on the insulating layer and having an opening exposing at least a portion of the pad. The protrusion protrudes from one surface of the pad and is buried in at least one of the insulating layer and the protective layer.
Claims18
A printed circuit board, comprising:
- a first insulating layer;
- a pad disposed in the insulating layer and having a protrusion;
- another pad disposed on the insulating layer;
- and
- a protective layer disposed on the insulating layer and having an opening exposing at least a portion of the pad and of the another pad,
- wherein the protrusion protrudes from one surface of the pad and is buried in the insulating layer, and
- wherein a top surface of the another pad is higher than a top surface of the pad and lower than a top surface of the protective layer.

A printed circuit board, comprising:
- an insulating layer;
- a pad buried in the insulating layer to be exposed to one surface of the insulating layer and including a first metal layer and a second metal layer disposed on the first metal layer;
- another pad disposed on the insulating layer;
- a protective layer disposed on the insulating layer and having an opening exposing at least a portion of the pad and of the another pad;
- and
- a conductive post disposed in the opening of the protective layer, protruding from the protective layer, and connected to the pad,
