Trimmer and method for regulating resistance value of resistance component as well as electronic device

Abstract

The invention provides a trimmer for regulating resistance value of a resistance component and a regulating method. The trimmer comprises a platform, a processor, a detection device and a trimming device. The method comprises the following steps: placing the resistance component on the platform; detecting the resistance values of the resistance component by use of the detection device, feeding back one detected resistance value to the processor and comparing the detected resistance value with a preset resistance value, thus obtaining a differential resistance value; and according to the differential resistance value, indicating the trimming device to cut the resistance component until the resistance component reaches the preset resistance value by virtue of the processor. The method provided by the invention can be used for detecting the resistance value of the resistance component and also carrying out mechanical cutting on the resistance component so as to simplify the operating complexity and improve the processing speed; and meanwhile, the electronic device which has the advantages of high precision and low error rate can be stably produced and the processing cost can also be lowered.

Problems solved by technology

[0005] However, the laser resistance trimming machine is used to trim the resistance value of the resistor. Because the laser trimming machine is expensive, the processing cost of the resistor remains high, and there are many factors that need to be controlled (such as power, cutting speed, delay time, etc.) etc.), which increases the difficulty of high-precision resistance trimming, thus affecting the accuracy of resistance trimming

In addition, as the size and structure of resistor products change, such as the design of metal sheet resistors, it becomes more difficult to control the resistance without damaging the other layers of the resistor while using the laser trimming machine.
