Alumina ceramic packaged thermistor and preparation method thereof
The invention provides an aluminum oxide ceramic packaging type thermistor and a preparation method thereof, the aluminum oxide ceramic packaging type thermistor comprises a ceramic chip, a silver electrode is attached to the side part of the ceramic chip, and a tin soldering sheet is arranged on the surface of the silver electrode; the tin soldering sheet is welded with a lead, the ceramic chip is coated with a silicone resin encapsulating layer, and the lead extends out of the silicone resin encapsulating layer; the silicone resin encapsulating layer is arranged in the aluminum oxide ceramic shell, and a mixed filling layer is arranged between the silicone resin encapsulating layer and the aluminum oxide ceramic shell. According to the thermistor packaged by the aluminum oxide ceramic shell made of aluminum oxide ceramics, circuit fire caused by failure of the thermistor can be avoided, the aluminum oxide ceramic shell resistor is low in surface temperature rise, high in dissipation coefficient, stable in installation and not prone to deflection, the safety and reliability of the thermistor in circuit work are effectively improved, and the service life of the thermistor is prolonged. Therefore, the thermistor can play a role in suppressing surge current and protecting a post-stage circuit.
本发明提供一种氧化铝陶瓷封装型热敏电阻及其制备方法，包括陶瓷芯片，所述陶瓷芯片的侧部附着银电极，且所述银电极的表面设有锡焊片；所述锡焊片焊接引线，所述陶瓷芯片的外部包覆硅酮树脂包封层，所述引线外伸所述硅酮树脂包封层；所述硅酮树脂包封层设于氧化铝陶瓷壳体的内部，且所述硅酮树脂包封层与所述氧化铝陶瓷壳体之间设有混合填充层。本发明采用氧化铝陶瓷形成的氧化铝陶瓷壳体封装的热敏电阻，可以避免因热敏电阻失效电路起火，且氧化铝陶瓷壳体电阻表面温升低，耗散系数高，同时安装稳固不易歪斜，有效地提高热敏电阻在电路工作的安全性和可靠性，使得热敏电阻可以电路起到抑制浪涌电流保护后级电路的作用。
