[0002] Although the more common components used in temperature sensors include bimetallic thermocouples, thermistors, platinum resistors, temperature-sensitive ferrites, etc., in the fields of automobiles and household appliances, the most commonly used are NTC thermistors, which are low-priced, high-precision, and reliable.

[0003] NTC (positive temperature coefficient) thermistor ceramic is a widely used semiconductor ceramic material. During the manufacturing process, an ohmic electrode layer must be made on its surface to eliminate the surface potential barrier of the NTC ceramic so that a good ohmic contact is formed between the electrode layer and the ceramic body. At the same time, a slurry layer needs to be made on the ohmic electrode layer so that it can be brazed with the lead or pin. The electrode slurry used in the traditional process of NTC thermistor is generally silver or gold electrode slurry, which has good mutual melting with tin.

[0004] In order to maintain the continuity of production on the thermistor automated production line, the slurry jig needs to be set at the slurry dipping process location, and the slurry is smeared on the jig. However, since the jig is placed sideways, the slurry is likely to flow off the jig, so the slurry needs to be applied manually continuously, which not only increases the workload of the workers, but also causes great waste of production materials.
