2. Description of the Related Art When a semiconductor device or the like is mounted on a circuit board by a bonding apparatus, the parallelism between the tool and the stage on which the circuit board is installed is extremely important, and it affects the reliability of the joint. . A conventional method for parallelizing bonding tools will be described with reference to FIG. First, bonding tools
The tool holding mechanism is a tool holder to which the tool 51 is fixed.
52, a tool holding part 53 for holding the tool holder 52, and an X-direction adjusting jig 54 and a Y-direction adjusting jig 55 attached to the tool holding part. The X-direction adjusting jig 54 and the Y-direction adjusting jig 55 are included in the tool 5.
The parallelism of 1 is adjusted. Tool 52 and station
A pressure sensitive paper 57 is used as a general method for parallelizing the dice 56. The pressure-sensitive paper 57 changes color only when pressure is applied. As shown in FIG. 7, the pressure-sensitive paper 57 is placed between the tool 51 and the stage 56 to apply pressure with the tool 51 to remove the pressure from the impression. Read the parallelism of the tool 51. When the parallelism is reached, the parallelism is re-established by adjusting the X-direction adjusting jig 54 and the Y-direction adjusting jig 55, and the pressure-sensitive paper 5 is read again.
Confirm by 7. The tool 51 is adjusted by repeating this operation several times. See tool 51
This pressure-sensitive paper 57 cannot be used when is used at a high temperature (300 to 500 ° C.). In this case, instead of the pressure sensitive paper 57, a polyimide tape coated with an adhesive is often used. This polyimide tape generally uses a film carrier used in the TAB system. Similarly, this is also installed between the tool 51 and the stage 57, and is pressed by the tool 51 from the polyimide tape side. Can be read and the parallelism of the tool 51 can be read. Hereinafter, the method of adjusting the parallelism is the same as that when the pressure sensitive paper 57 is used.

However, the above-mentioned conventional methods have the following problems. 1. When obtaining parallelism with a pressure-sensitive paper or a polyimide tape, pressure is applied each time and the parallelism is adjusted by observing the result, which requires considerable time and skill. Therefore, it takes time to obtain the parallelism of the tools at the time of switching the product type, which lowers the operation rate of the device, and consequently increases the mounting cost. 2. High precision is required for the parallelism of the tool,
A parallelism of 0.5 μm or less is required at a distance of 5 mm.
However, since the thickness of the pressure-sensitive paper used is about 100 μm and the thickness of the adhesive layer of the polyimide tape is about 30 μm, it is very difficult to adjust the parallelism of 0.5 μm or less. Difficult to do. In view of the above problems, the present invention provides a method and apparatus for adjusting the parallelism of a bonding tool very easily and highly accurately.
