  • Publication number: 20250098512
    Abstract: A suction unit control method includes simulating an air flow about a suction port, through which fumes generated when a laser beam is radiated on a target substrate on a stage unit to cut the target substrate are sucked up, installing an air blower on three or four sides around a laser cutting end at a height close to the suction port, controlling on and off of first to fourth solenoid valves of the air blower based on a movement of the stage unit while performing laser cutting on the target substrate while moving the stage unit.

  • Publication number: 20240313153
    Abstract: The disclosure provides a pressure detection method of a bonding device and a bonding system. The pressure detection method of a bonding device includes forming a backplane substrate including a light emitting element, disposing a pressure detection sheet on the backplane substrate, transferring the backplane substrate and the pressure detection sheet into a chamber, bonding the light emitting element by pressurizing the pressure detection sheet, photographing the pressure detection sheet, and detecting a color developing area of the pressure detection sheet. In the pressure detection method of the bonding device and the bonding system, it can be inspected whether uniform pressure is applied to a pressure detection sheet.
