Research On The Application Of Laser Trimming Technoligy In Laser Resistor Trimming Machine

Methods and elements in the application of micro-adjusting resistor by film was summarized in this article, the application of laser micro-adjusing technology in it had been introduced particularly, of which the theory model had been established, base on this model ,laser parameters and the processing of resistor micro-adjusting had been analized:in order to make sure the quality of resistor adjusting, the laser energy should transferred to the underlay;At the same time, we should control the laser enegy to avoid bring chap on it. The structure and elements of laser resistor trimming machine also had been introduced roundly, major units in it were designed and analyzed particularly, after that the design elements were brought forward.The common used shape and patch of micro - adjusting resistor were introduced,and various reasons which affect the laser resistor-adjusting's quality and precision had been summarized. After analyzed all kinds of factors, put forward the measurement to ameliorate them. According to the experimentation, the quality of resistor-adjusting and the relationship between some elements had got, theory analyzing and results of experiment may provide guidance for the debugging and application of resistor-adjusting.
