Embodiment 1

[0029] As shown in accompanying drawings 2, 4, 5, 6, 8, and 9, the chip thermistor derived by the method disclosed in the present invention includes an insulating ceramic substrate 200, a back electrode 201, a surface electrode 202, a thermistor Layer 203, protective layer 204, terminal electrode 205, intermediate electrode 206, and external electrode 207, the implementation method is as follows:

[0030] (1) On the surface of an insulating ceramic substrate 200, draw grooves vertically and horizontally according to the set intervals to form a grooved surface with a square continuous grid, and set the longitudinal groove L2, the horizontal groove L3 and the grooved surface as the front 1. The back side of the grooved surface is the reverse side; (It should be noted that the overall characteristics of the same insulating ceramic substrate are consistent, and which side is scratched is random. The setting of the grooved surface and the front and back sides here is Artificially d...

Abstract

This invention discloses a manufacturing method for slice thermal resistors, which prints a back electrode on the back of a marked slot side of an insulated ceramic chip, prints a face electrode on the slot side, then prints a thermal resisting layer and a protection layer with a thick film silk screen, which can reduce the processing time of slice thermal resistors effectively.

Description

technical field [0001] The invention relates to a method for manufacturing a thermistor of an electronic component, in particular to a method for manufacturing a chip thermistor. Background technique [0002] At present, there are many designs of chip thermistors disclosed in various forms. The main structure of these chip thermistors is (see attached drawing 1), a rectangular resistor body, coated with terminal electrodes and electroplated at both ends, and coated or not coated with a protective layer on the resistor body, which includes: resistor body 101 , glass encapsulation layer 102 , end electrode 205 , intermediate electrode 206 , and external electrode 207 . The manufacturing method of this type of chip thermistor includes the following steps: A: making a resistor body, the material is the oxides of transition metals Mn, Co, Cu, Ni, Fe, they are first mixed in a certain proportion and ground with a ball mill, and dried , and then pressed into tablets, sintered, an...
