Description

Technical Field

[0001] The utility model relates to the technical field of chip mounters, in particular to a single-station airbag chip mounter. Background Art

[0002] There is currently a sapphire wafer that needs to undergo surface grinding. Due to the thin thickness of the wafer, which is only 0.5 mm, the wafer cannot be directly placed on a grinder for grinding. The wafer needs to be attached to a ceramic plate carrier first, and then the ceramic plate carrier is placed on the grinder for grinding. However, bubbles are likely to appear during the process of attaching the wafer to the ceramic plate, resulting in the wafer not being in a flat state. Grinding in this state will seriously affect its quality. Utility Model Content
