Description
technical field [0001] The invention relates to the technical field of electronic component preparation, in particular to a PTC thermistor ceramic production line. Background technique [0002] Positive temperature coefficient thermistor, referred to as PTC thermistor, is a typical semiconductor resistor with temperature sensitivity. When it exceeds a certain temperature, its resistance value increases stepwise with the increase of temperature. PTC thermistor is a sensitive component with early development, various types and mature development. It is widely used in fields related to electronic and electrical temperature control such as batteries, security, medical treatment, scientific research, industrial motors, and aerospace. When PTC thermistor ceramics are used as heating components, the key characteristics required are high withstand voltage, low power attenuation and high current shock resistance. The PTC thermistor ceramic components produced by the existing process...
