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.

Abstract: A device for inserting a flexible printed circuit board into a connector includes: a gripper to which the flexible printed circuit board is securable; a deformer movably connected to the gripper; and a transporter connected to the gripper and the deformer. Movement of the deformer relative to the gripper, applies a transformation force from the deformer to a portion of the flexible printed circuit board to bend the portion about edges of the gripper, and transportation of the transporter transports the gripper together with the flexible printed circuit board which has the portion of the flexible printed circuit board which is bent about the edges of the gripper, toward the connector, and inserts the flexible printed circuit board into the connector.

Abstract: An inkjet print apparatus includes a print head discharging ink onto a substrate, the print head including a first heater; a reservoir storing the ink; a first pipe supplying the ink to the reservoir; a second pipe collecting surplus ink; a mixing unit located on the first pipe and mixing the ink; a pump located on the second pipe and pressurizing and supplying the surplus ink to the reservoir; a temperature sensor located between the mixing unit and the print head and sensing a temperature of the ink; and a controller controlling a temperature of at least one of the first heater and the second heater in response to information received from the temperature sensor. The print head includes a heat insulator blocking heat emitted from the first heater between the substrate and the first heater.
