Description
Technical Field
The utility model belongs to design circuit component field, especially alloy resistor.
Background
Chip resistors are becoming popular with more electronic enterprises due to their small size, high accuracy, high stability, low assembly cost, and the like. The current chip resistors mainly include thick film resistors, thin film resistors, metal foil resistors, pure gold resistors, and the like according to structural division. This patent is directed to a structure of a pure gold resistor and a method of manufacturing the same.
The main structure of the alloy resistor is mainly metal, and generally has the characteristics of simple structure, good heat dissipation, high power, high precision and the like. However, as with other types of resistors, heat generated when current flows through the resistor may be collected in the middle region of the resistive element that is farther from the electrodes, resulting in a change in the resistivity of the material in the heat collection region, a corresponding shift in the resistance of the resistor, and in severe cases, damage to the resistor. Secondly, because heat is concentrated in the middle region of the resistor element and is not transferred from the lower resistivity electrode to the bonded substrate in time, most of the heat can only escape into the air, causing the ambient temperature around the resistor to rise, which affects the normal use of the surrounding elements.
