Abstract

The invention relates to a structure of a sensing component of negative temperature coefficients and a manufacturing method thereof. The manufacturing method includes the following steps: preparing an alumina base plate; coating a conductive electrode at the back surface of the base plate with silver paste; manufacturing a lower electrode at the front surface of the base plate with the silver paste; coating a resistant layer above the lower electrode with resistant paste; coating a layer of upper electrode above the resistant layer; finishing the procedures with laser and vertically cutting a gap which goes through the layer of upper electrode; coating the upper electrode, the resistant layer and the lower electrode as a protecting layer with the epoxy resin (Epoxy); making a terminal electrode with nichrome alloy; stripping every lump unit; coating a nickel coating and a tin coating outside each lump unit so as to form good adhesion with a PC plate.

Description

technical field [0001] The invention relates to a structure of a negative temperature coefficient sensing component and a manufacturing method thereof, in particular that the sensing resistance value of the negative temperature coefficient sensing component can be adjusted by trimming the position of the upper electrode layer with a laser. Background technique [0002] Thermistor (Thermistor, the abbreviation of Thermal Resistor) is a resistor with a high temperature coefficient. As far as its resistivity is concerned, it belongs to a semiconductor; and according to its resistance value changing with temperature, it can be mainly It is divided into two types: negative temperature coefficient (NTC, Negative Temperature Coefficient) thermistor and positive temperature coefficient (PTC, Positive Temperature Coefficient) thermistor. [0003] NTC (Negative Temperature Coefficient of Resistivity, NTC) has the characteristics of high resistance at low temperature and low resistance...
