Abstract
A method for manufacturing connection structure, the method includes arranging conductive particles and a first composite on a first electrode located on a first surface of a first member, arranging a second composite on a region other than the first electrode of the first surface, arranging the first surface and a second surface of a second member where a second electrode is located, so that the first electrode and the second electrode are opposed to each other, pressing the first member and the second member; and curing the first composite and the second composite.
Claims9
A connection structure comprising:
- a first member having a first surface;
- a plurality of first electrodes located on the first surface;
- a second member having a second surface opposed to the first surface;
- a plurality of second electrodes opposed to the a plurality of first electrodes and located on the second surface;
- a first resin and conductive particles arranged between the at least one of the plurality of first electrodes and at least one of the plurality of second electrodes, the conductive particles including a particle core having elasticity coated with metals;
- and
- a second resin arranged between a first region surrounding the at least one of the plurality of first electrodes on the first surface and a second region surrounding the at least one of the plurality of second electrodes on the second surface,
- an insulating film arranged in the first region,
- wherein the second resin is in contact with the insulating film in the first region and the second surface in the second region, and the first resin and the second resin have different compositions from each other,
- wherein the conductive particles are arranged between the at least one of the plurality of first electrodes and the at least one of the plurality of second electrodes in a range of seven per 400 μm2 or more and twenty per 400 μm2 or less.
