发明名称 Method of manufacturing a circuit board
摘要 A method of manufacturing a circuit board, which includes a bump pad on which a solder bump may be placed, may include forming a solder pad on a surface of a first carrier; forming a metal film, which covers the solder pad and which extends to a bump pad forming region; forming a circuit layer and a circuit pattern, which are electrically connected with the metal film, on a surface of the first carrier; pressing the first carrier and an insulator such that a surface of the first carrier and the insulator faces each other; and removing the first carrier. Utilizing this method, the amount of solder for the contacting of a flip chip can be adjusted, and solder can be filled inside the board, so that after installing a chip, the overall thickness of the package can be reduced.
