Abstract
An electronic apparatus includes an integrated circuit board; a printed circuit board electrically coupled to first and second external circuits; and a ball grid array that couples the integrated circuit board and the printed circuit board, includes a first group including pieces of first ball grid, and includes a second group including pieces of second ball grid. The first group couples the first circuit block and the first external circuit. The second group couples the second circuit block and the second external circuit. The number of the pieces of first ball grid is larger than the number of the pieces of second ball grid. The minimum distance between the first group and the first side is shorter than the minimum distance between the group and the first side and is shorter than the minimum distance between the second group and the second side.
