Abstract

An electric device includes a semiconductor assembly, a circuit board, first conductive pads and second conductive pads. The circuit board has a chip-mounted area with a rectangular shape. The first conductive pads are arranged in a center zone or all corner zones of the chip-mounted area, and the second conductive pads are arranged within the rest in the chip-mounted area. The first conductive pads are respectively soldered to one part of solder joints of the semiconductor assembly through first solder-ball portions, and the second conductive pads are respectively soldered to another part of the solder joints of the semiconductor assembly through second solder-ball portions. Each of the second conductive pads is sized smaller than one of the first conductive pads, and a maximum width of each of the second solder-ball portions is greater than a maximum width of each of the first solder-ball portions.
