Abstract:
A heat bonding apparatus for manufacturing an ink-jet printhead of a printing apparatus by heat-bonding a flexible circuit tape onto an IC chip of an ink-jet printhead so that a signal from the printing apparatus can be transmitted to the IC chip of the ink-jet printhead to control the ink-jet printing operation, the heat bonding apparatus comprising:a head seat; a heat bonding head seated in the head seat, the heat bonding head being movable along with the head seat to carry out a heat bonding process; and a heat bonding sheet mounted on the heat bonding head and being deformable under pressure so that when the heat bonding sheet is pressed for heat bonding the flexible circuit tape and the IC chip, the heat bonding sheet undergoes deformation and in the mean time pushes the air away from between the flexible circuit tape and the IC chip to let them fully contact each other.
