Abstract
A detecting device for detecting the electrical connection between several first pads and second pads of a package substrate is provided. The first and the second pads are disposed on two opposite sides of the package substrate. The detecting device includes a socket unit, several first detecting components and several second detecting components. The socket unit is disposed on and coupled to the first pads. The first detecting components are disposed on and coupled to the socket unit. The second detecting components are disposed under and coupled to the second pads. The socket unit and the second detecting components are disposed on two opposite sides of the package substrate. While detecting, the first detecting components, the socket unit, the first pads, the second pads and the second detecting components are electrically connected sequentially, so as to determine whether the first pads are respectively and electrically connected to the second pads.
