Description
Technical Field
[0001] The utility model relates to the technical field of crystal bonding devices, in particular to a crystal bonding device for Mini RGB. Background Art
[0002] Mini LED, also known as sub-millimeter light-emitting diode, was first proposed by Epistar, meaning LED with a grain size of about 100 microns or more. Mini LED is a small lighting unit with a wide range of applications. Mini LED is composed of RGB three-primary color chips, and die bonding is one of the key processes that determine the reliability of Mini RGB components, so a die bonding device is used. There are at least the following disadvantages in the use of existing die bonding devices: 1. When using the existing die bonding device, the suction nozzle needs to move back and forth between the chip and the substrate. The time required to suck the chip and place it on the substrate is relatively long. Each reciprocating action is required to complete the placement of a chip, which reduces the efficiency of die bonding; 2. In order to ensure the fixing effect, the position of the substrate is fixed in the existing die bonding device, but it cannot meet the demand for die bonding at different positions of the substrate, which reduces the practicality. Therefore, we have launched a die bonding device for Mini RGB. Utility Model Content
