摘要: A printed circuit board is disclosed. The printed circuit board, which has at least one pad on which a solder ball is to be placed, includes a solder resist that covers a surface of the printed circuit board, an opening part that exposes the pad and supports the solder ball, and an extended portion formed in a perimeter of the opening part that allows an underfill to flow in between the printed circuit board and the solder ball. With this printed circuit board, the underfill can be filled in more readily between the printed circuit board and the solder balls, when mounting a component on the printed circuit board.

摘要: A manufacturing method of a package substrate is disclosed. The method for manufacturing a package substrate is by forming a bump on a bump pad in a core board, where a first circuit pattern including the bump pad is formed on one surface, a second circuit pattern electrically connected with the first circuit pattern is formed on the other surface, and a dielectric layer is selectively coated on the one surface such that the bump pad is exposed. The method includes layering a conductive layer on the other surface of the core board, coating a plating resist on the conductive layer, forming the bump by supplying electricity to the conductive layer to electroplate the bump pad, and removing the plating resist and the conductive layer. This makes it possible to omit the coining process and increase the density of the circuit by forming a fine bump by an electro tin plating method with small plating thickness deviation without designing additional plating bus lines, and improves the electrical performance without remaining plating bus lines.
