Patent ID: 10658327

Abstract:
Provided are a chip bonding apparatus and bonding method. The apparatus comprises: a chip supply unit (10); a substrate supply unit (20); a first pick-up assembly (30) arranged between the chip supply unit (10) and the substrate supply unit (20), comprising a first rotating component and a first pick-up head arranged on the first rotating component; a second pick-up assembly (40) comprising a second rotating component and a second pick-up head arranged on the second rotating component, wherein the first pick-up assembly (30) picks up a chip (60) from the chip supply unit (10) or the second pick-up assembly (40), and delivers the chip (60) onto a substrate of the substrate supply unit (20) to complete the bonding; and a vision unit (50) for realizing the alignment of the chip (60) and the substrate on the first pick-up assembly (30), wherein the chip supply unit (10), the substrate supply unit (20), the second pick-up assembly (40) and the vision unit (50) are respectively located on four work positions of the first pick-up head. The chip (60) is transported through rotation, improving the productivity of chip (60) bonding; and the chip (60) is reversed by utilizing the second pick-up assembly (40), which is compatible with two ways of bonding, i.e. a mark face of the chip (60) facing upwards and downwards.
