Problems solved by technology

[0003] However, the traditional sintering thermostats currently on the market have relatively single functions and are very inconvenient to use. When the traditional sintering thermostats are used, they cannot improve the sintering efficiency of the thermistor body, and make the thermistor body Uneven heating in the constant temperature box will easily cause the green body of the thermistor to crack and affect the sintering quality of the green body of the thermistor

Description

technical field [0001] The invention relates to the technical field of thermistor manufacturing, in particular to a sintering constant temperature box for thermistor manufacturing. Background technique [0002] Thermistors are a type of sensitive components. According to different temperature coefficients, they are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC). The typical feature of thermistors is that they are sensitive to temperature. , showing different resistance values ​​at different temperatures, positive temperature coefficient thermistors (PTC) have larger resistance values ​​when the temperature is higher, and negative temperature coefficient thermistors (NTC) have higher resistance values ​​when the temperature is higher Low, they belong to semiconductor devices, and generally in the manufacture of thermistors, sintering thermostats are required. [0003] However, the traditional sintering t...
