摘要： A flip chip BGA board is disclosed, in which each of the corners of the board is removed to minimize warpage of the board due to heat applied during the manufacturing process. Embodiments of the invention allow the production of thin boards by preventing warpage of the board, and may provide a board high in reliability since the risk of the chip being separated from the board is reduced.
