Abstract:
1. An electronic component bonding method comprising: an applying step of applying a metal fine powder paste on each of multiple electrodes that are provided on a substrate; a component placing step of placing multiple electronic components in positional alignment with the multiple electrodes respectively, the multiple electronic components including at least two electronic components that have different heights; an organic film placing step of placing an organic film on the multiple electronic components, the organic film having a thickness greater than a height difference between the highest electronic component and the lowest electronic component of the multiple electronic components; an organic film compressing step of pressing a pressing surface of a pressing member against the organic film, applying a first pressure to the electronic component side with the pressing member, and equalizing a height of a pressed surface of the organic film, the pressing surface having a planar shape, the pressing member being heated to a predetermined temperature, the pressed surface being pressed by the pressing surface; and a bonding step of pressing a compressing surface of a compressing member against the pressed surface, applying a second pressure to the electronic component side with the compressing member on heating for a predetermined time, and sintering the metal fine powder paste to bond electrode terminals of the multiple electronic components to the electrodes of the substrate respectively, the compressing surface having a planar shape.
