り混入等の対策とならないのが実状である。Such a glass diode has a structure, for example, as shown in the cross-sectional view in FIG. contact with the end surface of the heat sink 4 that has been removed. The pressure between this electric current wL2;3 and the heat sink 4 is created by the glass tube 5 that is fused to the 0I11 surface of the heat sink 4. At the same time, the chip 1 is sealed inside the glass tube. A lead wire 6 is welded to serve as an external connection. The manufacture of this glass tube diode involves inserting the diode chip 1 and both sinks 4 into the glass tube 5, and then inserting the diode chip 1 into the glass tube 5 in an adapted manner.
This is done by heating and fusing it to the heat sink 4. In this case, the problem is static electricity generated in the glass tube 5. Twist glass T1 is made of low-luka glass, for example, but static electricity is generated during transportation from the glass tube manufacturer and during storage, depending on the conditions.
When used in the reverse manufacturing process, dust and dirt are sucked up and encapsulated along with the chip. This static frost may prevent the chip from assuming its normal position, as shown in FIG. 2, and may impede encapsulation. In order to prevent kneading, glass tubes that have been delivered for static electricity removal treatment are generally grouped together, for example, 400
Heat treatment is performed at ℃ for 1 hour. However, even in this case, the material is charged with static electricity again before being used in the manufacturing process, and the actual situation is that it is not a complete countermeasure against dust contamination.
本発明は従って静電気の除去された状押でチップを封入
できるガラス管ダイオードの製造方法を提供することを
目的とする。Therefore, an object of the present invention is to provide a method for manufacturing a glass tube diode in which a chip can be encapsulated in a press in which static electricity is removed.

〜700℃で行オ)れる。The purpose of this is to insert a diode chip into a glass tube between two heat sinks, one end of which is connected to an IJ-do navy blue wire, and the other end of the glass tube connected to both heat sinks in a heating jig. In this method, only the glass tube is placed in a jig, and after a short heat treatment to remove static electricity, it is combined with other parts and glass-sealed at a higher temperature. Achieved by completing the process at 400°C for 1-2 minutes, the glass sealing is completed at 650°C.
It is carried out at ~700°C.

いし1/20に低減した。When this method is used, static electricity is removed from each glass tube used as a package for the glass tube diode, and the chip and heat sink can be inserted and sealed in a short period of time. There is no opportunity for this to occur, and sealing can be performed without any scum, dust, etc. In fact, the incidence of dust-filled products during the manufacture of glass tube diodes has been reduced to 1/10 to 1/20 compared to the conventional method.

挙げることができる。Another advantage of the present invention is that the cracks and cracks that occur when glass tubes are spread out on a stainless steel plate and cooled after extensive heat treatment to remove static electricity by conventional methods are completely eliminated. In the method of the invention, the glass tube is used immediately after static electricity has been removed, so there is no risk of this happening.

は極めて高い。Although the heat treatment conditions for removing static electricity according to the present invention will of course vary depending on the material of the glass tube, it does not require separate equipment for heat treatment and can economically reduce the defective rate during the manufacture of glass tube diodes. achievable and the results obtained are extremely high.
