Other Solutions

Eight modular test solutions — combined into one seamless line, tailored to your power module specifications.

Lab

Integrated line control, automated traceability, and real-time analytics - built for modern manufacturing workflows.
A centralized control plane that keeps every test step, laser process, and production record in sync - with a clean, modern interface that reduces cognitive load.

  • Integrated line computer controlling and monitoring every process and test step in real-time
  • Automated secure time stamps recorded for each individual test and laser process
  • Direct secure database handshake with client ERP / MES infrastructure
  • Centralized recipe and test program configuration management
  • Live OEE performance analytics, yield reports, and top failure rankings

Drawer Station

Secure manual testing station enabling sequential multiplexing and evaluation for any power semiconductor package.

A highly flexible, interchangeable handling unit that safely contacts, tests, and validates diverse device types with integrated process controls.

  • Universal compatibility for diodes, IGBTs, FET modules, and Si/SiC devices via easily exchangeable test-adapters
  • Automated 4-wire contacting (pogo pin or gripper) with secure drawer locking during active testing
  • Smart visual status indicators with automatic release for passed components and mandatory manual fail acknowledgment
  • Integrated hardware for fixed or handheld Data Matrix scanning to ensure complete database traceability
  • Built-in integration for side-mounted label printers, label dispensers, or direct inkjet marking

Diode Handler

Automated feeding, straightening, measuring, and sorting system optimized for high-volume, continuous diode processing.

A comprehensive mechanical handling unit that securely processes, contacts, and categorizes diodes into four distinct classes with continuous routing checks.

  • High-capacity 37-liter vibration bowl feeder processing up to 90 parts per minute
  • Integrated head wire straightener and separator for precise gap control and cutting
  • Spring-loaded, four-contact (force and sense) mechanical handling for reliable measuring
