Abstract
Provided is a conductive ball mounting method using an electrostatic chuck. According to the conductive ball mounting method using an electrostatic chuck, when the process of mounting conductive balls onto a substrate through mounting grooves formed in the mask is performed, the occurrence of process defects can be prevented and conductive balls having very small sizes can be effectively mounted on the substrate. According to the conductive ball mounting method using the electrostatic chuck of the disclosure, the process of mounting conductive balls can be performed with high quality by preventing deformation of the mask without missing of some of the conductive balls. According to the conductive ball mounting method using the electrostatic chuck of the disclosure, the process of mounting small sizes of conductive balls on the substrate can be effectively performed.
