。[Background Art] With the diversification of electronic industrial parts and their becoming shorter, smaller, lighter and thinner, the shapes of heat-resistant jigs used to manufacture electronic industrial parts have become complex and diverse. Because of its superiority, demand is increasing in response to these demands. Due to the nature of the graphite jig, it is necessary to accurately position and place many electronic components such as lead frames on the surface of the graphite jig body. For this reason, conventionally, metal pins for positioning electronic components at predetermined positions on a graphite jig have been driven into insertion holes in the jig body or screwed into the jig.

なくされたり、また余分の金属ピンを新規に立設して使
用せざるを得ないなどの経済上不利な点があった。However, graphite jigs have less hardness than metal pins and the material itself is relatively soft, so the metal pins may fall off or loosen due to shock or strong vibration during use or transportation. There were economic disadvantages such as a decrease in positioning accuracy, the inability to position electronic components, which forced work to be interrupted, and the need to install new extra metal pins. .
【０００４】また、この種の黒鉛製治具は、高温下で使

膨張率の差に充分注意をする必要がある。[0004] This type of graphite jig is one that is used at high temperatures (700 to 900
℃), so when graphite and metal members having different coefficients of thermal expansion are integrally provided, it is necessary to pay sufficient attention to the difference in the coefficients of thermal expansion.
【０００５】これとは別に、この種の黒鉛治具に使用さ

ある。[0006] Considering the above, the positioning pin used in the graphite jig generally has a different coefficient of thermal expansion from that of the graphite jig, and the difference in the coefficient of thermal expansion between the two is unavoidable. It is something. There is a need for a positioning pin that can absorb this difference in thermal expansion coefficient between the two.

The invention is characterized in that it consists of a composite body), and as the invention of claim 2, it comprises a graphite jig main body having an insertion hole into which a carbon fiber reinforced carbon material pin for positioning the graphite jig is inserted; , filling the gap between a carbon fiber-reinforced carbon material pin installed in the insertion hole and the tip of the pin and the insertion hole,
It is characterized by comprising an adhesive that fixes the metal pin in the insertion hole to the jig body.
【０００９】本発明においては、位置決めピンが炭素繊

すいという欠点を防止することができる。In the present invention, since the positioning pin is made of carbon fiber-reinforced carbon material, it can withstand use at high temperatures and, unlike pins made of graphite, can prevent the disadvantage of being easily broken.

を防止することができる。[0010] Also, in the case of metal pins, there was a problem that the main body of the graphite jig would crack due to the large difference in thermal expansion compared to graphite, but in the case of pins made of carbon fiber-reinforced carbon materials, the difference in thermal expansion It is possible to prevent the disadvantage that the jig main body is broken due to the difference in the temperature.

They are mutually restrained between the insertion holes of the tool body, and can prevent the carbon fiber-reinforced carbon material pin from loosening. This prevents the carbon fiber-reinforced carbon material pin from loosening or falling off.

Good. For example, the thermosetting adhesive described in Japanese Patent Application No. 60-281782 has excellent heat resistance and adhesive strength.
