Solder member mounting system
A solder member mounting method includes providing a substrate having bonding pads formed thereon, detecting a pattern interval of the bonding pads, selecting one of solder member attachers having different pattern intervals from each other, such that the one selected solder member attacher of the solder member attachers has a pattern interval corresponding to the detected pattern interval of the bonding pads, and attaching solder members on the bonding pads of the substrate, respectively, using the one selected solder member attacher.
