Abstract

PURPOSE: To prevent solder deposition on ceramics surface by first dipping the ceramics element connected with lead wires in an oil bath then dipping the same in a solder bath provided with an ultrasonic wave vibrator.
CONSTITUTION: Lead wires 3 are mounted to a ceramics element such as a voltage non-linear resistor 1 provided with electrodes 2 or the like is dipped in an oil bath 4 using silicone oil or the like having heat resistance. Thence, the resistor 1 and lead wires whose surfaces are covered with oil films are dipped in a solder bath 5 and ultrasonic vibrations are transmitted to the melted solder by an ultrasonic wave vibrator 6. Because of these ultrasonic wave vibrations, the oil films detach from the metal surfaces and the solder deposits. On the other hand, the oil films do not peel off from the ceramics surfaces and therefore no solder deposits thereon. If this element is taken out from the solder bath, the solder solidifies and the electrodes 2 and lead wires 3 are connected. By this method, the connection of the ceramics and lead wires 3 is accomplished without using flux.
