1. A substrate structure comprising:
a first printed circuit board having a first side and a second side opposing each other;
a second printed circuit board having a third side and a fourth side opposing each other; and
a plurality of passive components embedded in the first printed circuit board,
wherein the plurality of passive components includes a first group, including a plurality of first passive components disposed adjacent to each other, and a second group, including a plurality of second passive components disposed adjacent to each other,
a smallest distance between the first and second groups is greater than at least one of a smallest distance between adjacent first passive components of the plurality of first passive components or a smallest distance between adjacent second passive components of the plurality of second passive components,
the first printed circuit board is disposed on the second printed circuit board such that the first side of the first printed circuit board faces the fourth side of the second printed circuit board, and
the third side of the second printed circuit board includes an opening exposing a pad disposed in the second printed circuit board.
