THERMISTOR MANUFACTURING METHOD Russian patent published in 2025 - IPC H01C17/30 H05B3/10 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electronic engineering and specifically to production of thermistors, and can be used in electronic, radio engineering and other related industries. Method of making thermistors involves forming planar contacts on an insulating substrate by applying a conductive paste by screen printing, forming a resistive layer by applying a high-temperature resistive paste by screen printing, followed by burning-in. Conducting paste application is carried out under action of electromagnetic oscillations with frequency from 1 to 1.5 MHz and amplitude from 0.1 to 0.2 mV with further burning-in at temperature from 790 to 860 °C, and the resistive layer burning-in is carried out under the influence of pulse current with frequency of 250 kHz to 300 kHz with a pulse amplitude of 10 to 20 mV at temperature of 840 to 860 °C.

EFFECT: reduced spread of resistance of thermistors, increased yield ratio and reduced prime cost.
