本発明は、単位としての酸化物非直線抵抗体をハンダに
より接合強度大にして複数積層接合する酸化物非直線抵
抗体のハンダ接合方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for soldering oxide nonlinear resistors in which a plurality of unit oxide nonlinear resistors are laminated and bonded by increasing the bonding strength with solder.

が複数積層接合されて形成されている。2. Description of the Related Art In general, an oxide nonlinear resistor used, for example, in an earth arrester is formed by laminating and bonding a plurality of oxide nonlinear resistors as a unit.

ここに、通常、固相温度と液相温度との差が大きいハン

合強度を増大し得ると信じられている。Conventionally, in order to stack and bond a plurality of units of oxide nonlinear resistors, solder was interposed between each unit of oxide nonlinear resistors, as disclosed in, for example, Japanese Patent Application Laid-open No. 10154/1983. This was done by applying pressure and heating.
Here, it is generally believed that in the case of solder having a large difference between the solidus temperature and the liquidus temperature, the bonding strength can be increased by bonding at a temperature close to the liquidus temperature.

悪くなった。Therefore, conventionally, for example, the solidus temperature of solder is about 25
When the temperature was 0° C. and the liquidus temperature was about 297q0, the heating conditions were set at 285 to 29500, and soldering was performed under appropriate pressure conditions. Problems to be Solved by the Invention However, the heating conditions in the conventional soldering method described above have an extremely narrow allowable temperature range;
In addition to being difficult to control the temperature, when the temperature exceeds the allowable temperature range, the bonding strength decreases extremely, and the variation in bonding strength between the oxide nonlinear resistors in each unit increases, resulting in poor yield.

らなる組成とした。On the other hand, if the bonding strength is low, the fixing mechanism with a large pressing force becomes complicated and the lightning arrester becomes large, and when an impulse current due to lightning is applied to the lightning arrester, the stacking boundary surface with a small bonding strength becomes Sparks were generated, and as a result, the insulating oil deteriorated and the surface of the oxide nonlinear resistor was contaminated, resulting in flashover. Means and Effects for Solving the Problems In order to solve the problems, the present invention provides a structure in which a plurality of units of oxide nonlinear resistors are laminated, and a layer is formed between the oxide nonlinear resistors in each unit. In a method for soldering oxide nonlinear resistors using solder and applying pressure and heating, the solder contains 91 to 9a of lead and 4.5 to 5.5% of tin by weight. % by weight and the balance 3 to 4.5% by weight was composed of at least one of zinc, antimony, aluminum, titanium, and silicon.

The product name (manufactured by Asahi Glass Co., Ltd.) was used, and the pressurizing conditions were as follows.
50-300k9/ground, heating conditions 315-460
This was done as 00. Next, we actually measured the bonding strength with respect to the heating conditions (bonding temperature), and the results shown in FIG. 2 were obtained.

ような結果を得た。In Figure 2, the vertical axis shows the bonding strength and the horizontal axis shows the bonding temperature. When using Solder 2 with the above composition, the bonding strength is optimal when the heating condition is set to 315 to 46,000. It can be seen that the size is maintained. Temperature is 315oo
If it is less than 46,000, the reaction will be incomplete and the bond will not be good, and if it exceeds 46,000, the solder 2 itself will be oxidized and the bonding strength will actually decrease. Furthermore, when the bonding strength under pressure conditions was actually measured, the results shown in FIG. 3 were obtained.

・形化される。In Figure 3, the vertical axis shows the bonding strength and the machine axis shows the pressure force. When using solder 2 with the above composition, the bonding strength is is found to be in the most favorable condition. If the pressure is less than 50k9, the reaction will be incomplete and a good bond will not be formed, and if it exceeds 300k9, the molten solder 2 will be swept away from between the oxide nonlinear resistors 1. be. Effects of the Invention As described above, according to the present invention, using solder having a specific composition, the pressure and heating conditions are set to 50 to 300, respectively.
By limiting the resistance to k9/earth and 315 to 46,000, the bonding strength of the oxide nonlinear resistor is improved and the vibration resistance is improved. As a result, the fixing mechanism is simplified and lightning arresters etc. can be shaped. .
