  • Publication number: 20250226237
    Abstract: Provided is a method of mounting bonding material deposits, a method of mounting bonding material deposits in mounting recesses formed in a mask so that the bonding material deposits may be mounted on an electrode of a substrate. According to the method of mounting the bonding material deposits, an area of the region where the bonding material deposits are concentrated in the chamber is increased, and thus, small and light-weight conductive balls may be effectively mounted in the mounting recesses of the mask. Also, according to the method of mounting the bonding material deposits, because chances that the bonding material deposits come into contact with the mounting recesses in the mask increase, the bonding material deposits may be rapidly and thoroughly mounted in the plurality of mounting recesses formed in the mask.
