Definitions
- the heating start temperature characteristic map is a state in which the nonconductive film is sandwiched between the bonding stage and the bonding tool and pressed with a constant load from the various heating start temperatures to the same temperature. While lowering the temperature of the nonconductive film at a rising rate, measure the descent amount of the bonding tool, calculate the viscosity of the nonconductive film based on the descent amount of the bonding tool, and start the heating start temperature at the same temperature rising rate. It may be output as a change characteristic of viscosity with respect to the temperature of the nonconductive film when changing.
- the bonding apparatus 100 includes a bonding stage 10 for vacuum-sucking the semiconductor chip 32 on the surface, a bonding tool 24 for vacuum-sucking the semiconductor chip 31, a bonding head 20, and a control unit 90.
- the bonding head 20 includes a base 21, a heat block 22 attached to the base 21, and a drive unit 25 for driving the base 21 in the vertical direction.
- the bonding tool 24 is fixed to the heat block 22 by vacuum suction.
- the bonding stage 10 incorporates a heater 12 for heating the semiconductor chip 32, and the heat block 22 incorporates a heater 23 for heating the semiconductor chip 31. Connected to the heaters 12 and 23 are controllers 14 and 26 for adjusting the power supplied to the heaters 12 and 23, respectively.
- the control unit 90 is a computer that internally includes a CPU and a memory.
- the drive unit 25 of the bonding head 20 drives the bonding tool 24 in the vertical direction based on the command of the control unit 90, and outputs the height of the bonding tool 24 and the pressing load F of the bonding tool 24 to the control unit 90.
- the heat block 22 is attached with a temperature sensor 91 for detecting the temperature of the heat block 22. Further, a temperature sensor 92 for detecting the temperature of the NCF 40 is attached to the bonding apparatus 100.
- the temperature sensor 92 may be, for example, a non-contact temperature sensor. The temperature data acquired by the temperature sensors 91 and 92 is input to the control unit 90.
