Abstract

The invention relates to a resistor for precisely setting temperature coefficient and a manufacturing method thereof. The invention selects the thick film resistance serum with two temperature coefficients to manufacture a target thick film resistance. The temperature coefficients of two kinds of thick film resistance serum are taken at two sides of the temperature coefficient of the target thick film resistance. Furthermore, the resistance value of the target thick film resistance is the sum of the resistance values of two thick film resistances, and the resistance values of two thick film resistances are determined according to a formula. Two thick film resistances are precisely modified to correct the resistance values so that the temperature coefficient error of the target resistance is reduced to about 1 percent from the error about 12.5 percent in the prior art.

Description

technical field [0001] The invention relates to a thick-film resistance device and its manufacturing process, in particular to the repairing of the thick-film resistance device, especially the method for repairing the thick-film resistance device by laser. Background technique [0002] In the prior art, in many temperature-controlled electronic systems, it is necessary to have an accurate temperature coefficient between the electrical signal output by the temperature sensor and the temperature change to quantify, but in practical applications, the temperature coefficient of the resistance temperature sensor directly affects Whether the temperature measurement is correct or not. Therefore, the pursuit of high-precision temperature coefficient of resistance is the goal of many resistance temperature sensor manufacturers. [0003] For example, the Chinese invention patent application with application number 200610051337.0 discloses a kind of "resistor with adjustable temperatu...
