Patent ID: 7026188

Claim:
A manufacturing method of an electronic device comprising the steps of: preparing a printed wiring board having a first region and a second region which differ from each other over one main surface thereof, a first electronic component having a plurality of first projection electrodes over one main surface thereof, and a second electronic component having a plurality of second projection electrodes which have a melting point higher than a melting point of the first projection electrodes over one main surface thereof; mounting the first electronic component to the first region of one main surface of the printed wiring board by melting the plurality of first projection electrodes; and mounting the second electronic component to the second region of one main surface of the printed wiring board by compression-bonding the second electronic component while heating in a state that an adhesive resin is interposed between the second region of one main surface of the printed wiring board and one main surface of the second electronic component, wherein the step of mounting the second electronic component is performed after the step of mounting the first electronic component.
