Real-time electrical feedback meets laser ablation precision. Eliminate resistor variance in thick & thin film hybrid circuits.
The LT50x0 series by Photonics Systems Group (PSG) is a high-precision laser trimming system designed to adjust resistance values and electrical properties of electronic components, sensors, and hybrid circuits in real time. During processing, the circuit is continuously monitored via a probe card connected to the system's integrated measurement unit. The laser ablation stops automatically once the target value is reached. The non-contact, wear-free process produces no residue or mechanical stress. Multiple laser sources (UV, IR) support both thick and thin film materials. Open software architecture enables integration of third-party hardware and custom algorithms. Flexible automation from stand-alone to fully inline configurations. Backed by PSG's track record of 2,000+ successfully implemented machine projects worldwide.
