ABSTRACT:
A method of mounting electronic components on circuit boards, which includes the steps of obtaining a bonding film member by filling bonding material into openings in a predetermined pattern of an electrically-insulating and heat-proof film and holding the bonding material in the openings by a flux layer laminated on one surface of the film, overlaying the bonding material of the bonding film member onto conductive layers of a circuit board by supplying the bonding film member onto the circuit board, superposing electrodes of electronic components onto the bonding material of the bonding film member by supplying the electronic components onto the bonding film member, and melting the bonding material by heating the circuit board.
