Disk bonding method and system

摘要

A disk bonding system or method comprises a first element (N1) for forming an annular adhesive layer (35) on an upwardly facing joint surface of a lower side disk (DL), and a second element (N2) for forming a dotted adhesive layer (33) on a downwardly facing joint surface of an upper side disk (DU). Then, a third element sets the upper and lower side disks in a confronting state, and reduces the spacing between the upper and lower side disks until the annular adhesive layer and the dotted adhesive layer are sandwiched between the upper and lower side disks. During this, the annular adhesive layer and the dotted adhesive layer are brought into contact with each other, and the contact region expands in a manner to prevent occurrence of bubbles.
