Method of manufacturing bump-component mounted body and device for manufacturing the same

摘要

Bump components mounted on a circuit board on a supporting substrate is covered with a flexible separation wall. A pressure difference is provided between the inner and outer sides of the separation wall and thus the bump components are pressed against the circuit board. When heating is carried out in this state, the bump components and the circuit board are connected with a conductive adhesive or solder. During the heating, the circuit board is not deformed. Therefore, a bump-component mounted body can be manufactured with high yield.
