How to do laser trimming on thick and thin-film resistors

The laser resistor trimmer is a precise laser trimming device. It changes the conductive cross-sectional area of ​​the resistor body by short-pulse laser scanning cutting to achieve the trimming of the resistor body below the target resistance value to within the tolerance range of resistance value Suitable for rapid mass production of chip resistors. The industrialization of precision laser trimmers can speed up China's comprehensive mastery of lithography machine technology. The simple resistance trimming solution, the standard laser resistance trimmer solution and the online function laser resistance trimmer solution can meet the needs of different industries and different processes.

5. Functional signal interface: the principle of laser trimming resistance (laser trimming resistance) according to the circuit function requirements

In order to improve the accuracy of the thick film circuit, the resistance must be adjusted. Due to the inherent inaccuracies of the thick film screen printing operation, the unevenness of the substrate surface and the non-repetition of the sintering conditions, positive and negative errors often occur in the thick film resistor. After the bottom printing is fired, the resistance value is about 30% lower than the target value, so the target value must be reached by laser adjustment.
