ELECTRONIC COMPONENT BONDING METHOD

摘要

The present invention ensures a good bonding state between the electrode terminals of electronic components and the electrodes of a substrate, and achieves an increase in productivity and a downsizing of the substrate. The present invention includes: 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 with different heights, on the multiple electrodes, respectively; an organic film placing step of placing an organic film on the multiple electronic components; an organic film compressing step of applying a first pressure to the electronic component side with a pressing member and equalizing the height of the organic film; and a bonding step of applying a second pressure to the electronic component side with a compressing member on heating for a predetermined time and sintering the metal fine powder paste.
