Next, the operation of the thermocompression bonding head 20 will be described with reference to the operation diagram of FIG. 7 and the time chart of FIG. Initially, the thermocompression-bonding member 35 is in the raised position shown in FIG. 7A, and the enlarged portion 35a is preheated to about 200 ° C. by the heater 37. When the rod 24 of the air cylinder 23 is projected downward at the timing t1, the thermocompressor 35 is lowered and the grounding portion 35b is grounded to the film carrier 5 with a weak force (see FIG. 7B). If the thermocompression-bonding member 35 is grounded to the film carrier 5 with such a weak force, it is possible to prevent the display panel 1 from being damaged by an impact at the time of grounding. At this time, the pressure sensitive value of the pressure sensitive element 28 is 1.0.
It is kg / cm 2 . Simultaneously with this grounding, the valve 46 is opened and cold air is blown from the blowout hole 42 to the upper surface of the film carrier 5 near the grounding portion 35b to prevent the temperature of the film carrier 5 from rising, and the film carrier 5 is weakly force for a predetermined time. Is pressed by the thermocompressor 35.

2), the lead 7 is strongly pressed against the electrode 2 of the display panel 1. At the same time, the valve 46 is closed and the film carrier 5 is formed by blowing cold air from the blowout hole 42 of the pipe 41.
Cooling is stopped, and the temperature of the film carrier 5 rises sharply. In this way, when the heating of the film carrier 5 by the grounding portion 35b and the pressing state with a strong force are maintained for a certain period of time, the conductive sheet 3 is cured at the timing t3,
Immediately after that, at timing t4, the air cylinder 23
The rod 24 is retracted, the thermocompression-bonding element 35 starts to move upward to release the pressed state against the film carrier 5, and the series of operations is completed. The cycle time T is about 30 seconds.
