ABSTRACT:
An absorber head picks up a plurality of soldering balls from a container, and is shifted horizontally toward a substrate. In the midway of this shift movement, the absorber head is stopped just above a flux storage and then lowered to soak the soldering ball in the flux stored in the flux storage, thereby applying each soldering ball with an adequate amount of flux. Thereafter, the absorber head is again shifted horizontally until it reaches the substrate. Then, the absorber head lowers the soldering ball applied with flux, so that each soldering ball is mounted on a corresponding electrode provided on the substrate. If any soldering balls are left in the flux storage due to failure of the pickup operation by the absorber head, such soldering balls are surely collected in a groove by wiping movement of a squeegee which is associated with the flux storage.
