Ultralow-Resistance Laser Resistor Trimmer
Ultralow-resistance laser resistor trimmer. A micrometer-scale laser spot scans the resistor surface, melting and vaporizing the resistive paste layer to form a groove of specified depth and change conductive cross-section or length. A precision measurement system measures resistance in real time and stops emission at the target, bringing an initially lower resistance into the required tolerance. A key system in ultralow-resistance resistor production, it trims varied formats, including ceramic, PCB, leadframe, and individual resistors. Resistance range:0.1mΩ-1Ω. Trimming accuracy:±0.1/±0.5/±1(%).
