Method of producing thermistor chips

摘要

Thermistor chips are produced by preparing thermistor bodies each having outer electrodes formed on its end parts and dipping them in a solvent so as to melt away exposed surface portions of the thermistor body. In order to efficiently adjust their resistance values so as to produce thermistor chips with resistance values having only small variations from a target value, the resistance value between the outer electrodes are measured for each and they are divided into ranks according to the measured resistance values, and the dipping process is carried out differently for different ranks such that different amounts of the thermistor body material will be melted away.
