Abstract: A process of transferring a flux on electrodes of a semiconductor chip, a film carrier, or a substrate, the process comprising: using a transfer apparatus including a transfer baseplate having protrusions corresponding to said electrodes; dipping the tips of the protrusions of the transfer baseplate in a flux bath to cause the flux to stick to the tips; then aligning the protrusions of the transfer baseplate with the electrodes; and transferring the stuck flux onto the electrodes from the tips.

Abstract: A process of producing small metal bumps includes the steps of simultaneously holding small metal balls on an arrangement baseplate in the positions corresponding to those of electrodes of a semiconductor chip, a film carrier, or a substrate; aligning the small metal balls held on the arrangement baseplate with the electrodes; lightly pressing the small metal balls against the electrodes; to provisionally fix the balls to the electrodes; and pressing the provisionally fixed small metal balls to flatten the pressed surfaces of the small metal balls, and at the same time, to bond the small metal balls to the electrodes.
