Abstract

PURPOSE: To apply a fixed quantity of liquid by immersing a part of lower side of a rotating roller in a liquid container, connecting a driving device to allow free rotation and making the exposed upper part of the rotating roller a taking- out part for the said liquid.
CONSTITUTION: An adhesive 7 is contained in a container 15 to a position about 1/3 of the diameter of a rotating roller 13. With continuous rotation of the rotating roller 13, new adhesive adheres incessantly on the outer circumferential face of the rotating roller 13 and a fixed thickness (d) is maintained. When the back of a chip 4 comes into contact with the take-out part 20 in the upper part of the rotating roller 13 on which the adhesive 7 of a fixed thickness (d) adheres, a fixed quantity of the adhesive is continuously applied on the back of the chip 4 by surface tension. By this way, a fixed quantity of liquid adheres to the chip, and thereby joining of the chip can be effected surely and stably.
