Abstract: An imprint method includes: applying a applying a material for forming a patterned layer having a pattern, to a substrate; feeding a stamp film including a stamp pattern corresponding to the pattern of the patterned layer, along a pressure roller and an idle roller; forming the patterned layer having the pattern, including: the pressure roller pressing the stamp film toward the material to contact the stamp pattern of the stamp film with the material layer, curing the material layer in contact with the stamp pattern, and moving the pressure roller and the idle roller to peel the stamp film off the cured material layer by a peeling force, to form the patterned layer having the pattern; and detecting a defect in the formed patterned layer, during the peeling of the stamp film, by sensing the peeling force in real time by a pressure sensor connected to the pressure roller.

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.
