Abstract
In a mounting structure of a flip chip IC, the flip chip IC is mounted on an alumina laminated substrate through conductive lands of the substrate and bumps of the flip chip IC. A space between the flip chip IC and the substrate is filled with resin. Further, inspection lands are provided on the substrate for inspecting the flip chip IC, and are electrically connected to the conductive lands through vias and inside wires provided in the substrate. That is, the inspection lands are connected to the conductive lands to bypath an edge portion of the resin. As a result, separation of the resin from the substrate can be prevented.
