Abstract
A device for loading electro-conductive ball onto the terminal regions of a substrate more correctly and reliably is disclosed. Micro-ball loading device (200) may have the following parts: backing plate (220) supporting substrate (100) such that plural terminal regions (108) formed on one surface of substrate (100) are free, transfer mask (210), which contains a metal mask and has plural through-holes (216) formed corresponding to plural terminal regions (108) of the substrate, fixing block (230) onto which end portions (210a) of the transfer mask are fixed such that transfer mask (210) faces one surface of the substrate, and magnet part (240), which attaches transfer mask (210) by magnetic force to the side of backing plate (220); for magnet part (240), the attachment force to the center portion of the substrate is less than that of the peripheral edge portion.
