In this manner multiple pieces of uniform media can be adhered in an ever increasing number precisely positioned as determined by computer software and the computer controlled apparatus. Objects and prototypical shapes can then be created by the combination and adhesion of all the media parts.

Abstract: Disclosed is a sealant dispenser for more precisely dispensing a sealant onto a substrate, and a control method thereof.

Also, by minimizing the distance between the nozzle and a measuring point provided by the distance sensor, it becomes possible to dispense the sealant at higher precision.

Abstract: When an electronic component is mounted on a substrate, the electronic component is first placed on the substrate with a solid support interposed between the electronic component and the substrate. The solid support serves to space a terminal conductor of the electronic component from a corresponding terminal pad on the substrate. A conductive bonding material is then melted on the terminal pad. The melted conductive bonding material gets exposed to the peripheral atmosphere over a larger area. Even if a bubble is generated within the melted conductive bonding material, the bubble is allowed to easily get out of the melted conductive bonding material. Removal of the gas is promoted in the melted conductive bonding material. The solid support is subsequently melted. The electronic component is moved down toward the substrate, thereby contacting the terminal conductor with the melted conductive bonding material on the corresponding terminal pad.
