Overview
The ZOLIX Chame-3000 LED Source/Meter is a purpose-built, integrated electro-optical test instrument engineered for high-throughput LED production line validation and binning. Unlike generic source meters or standalone spectroradiometers, the Chame-3000 implements synchronized electrical stimulus and optical acquisition in a single hardware platform—enabling concurrent measurement of forward voltage (VF), reverse leakage current (IR), polarity, and full spectral radiometric data (including luminous intensity, chromaticity coordinates x/y, dominant wavelength λd, peak wavelength λp, centroid wavelength λc, FWHM, CCT, and CRI). Its architecture follows the principles of calibrated photometric traceability, with optical measurements referenced to NIST-traceable standards and electrical measurements conforming to IEC 62031 and JEDEC JESD51-1 guidelines for LED parameter characterization.
Key Features
- Simultaneous IV + spectral acquisition: Real-time correlation between electrical drive conditions and optical output enables accurate thermal drift compensation and junction temperature estimation.
- Modular configuration: Six selectable electrical modules (Chame-3000-SL1/SL2/SL3/SH1/SH2/SH3) support varying speed–accuracy trade-offs (20–120 ms per measurement) and current ranges (0–500 mA or bipolar ±1500 mA), accommodating low-power indicator LEDs through high-power COB packages.
- Integrated polarity detection: Automatic forward/reverse bias identification prevents misorientation during automated testing and ensures consistent orientation-dependent measurements (e.g., for asymmetric chip designs).
- Programmable preheat and power-on timing: Enables standardized thermal stabilization protocols prior to measurement—critical for repeatable VF and chromaticity assessment per LM-80 and TM-21 requirements.
- Current-limiting protection: Hardware-enforced current ceiling safeguards both DUTs and internal circuitry during transient overloads or short-circuit events.
- USB 2.0 interface with deterministic latency: Ensures deterministic trigger synchronization between source output and Chameleon SpectroRadiometer (e.g., Chame-LH200) acquisition, eliminating jitter-induced spectral smearing.
Sample Compatibility & Compliance
The Chame-3000 supports standard LED package formats including 0402, 0603, 0805 SMD, T-1¾, PLCC-2/4/6, and high-power MCPCB-mounted emitters. It complies with ISO/IEC 17025 calibration traceability frameworks when used with ZOLIX-certified calibration kits. Optical measurements adhere to CIE S 025/E:2015 for LED photometry and spectroradiometry, while electrical test routines align with IEC 60839-11-2 (LED electrical safety) and JEDEC JESD22-A114 (ESD sensitivity classification). The system supports audit-ready data logging required under GLP and GMP environments, including timestamped operator ID, environmental sensor metadata (optional ambient temperature/humidity input), and version-stamped firmware revision tracking.
Software & Data Management
ZOLIX Chameleon Software provides a unified GUI for hardware orchestration, measurement definition, and bin logic construction. All settings—including spectroradiometer integration, handler communication (RS-232/IO TTL), and multi-stage binning rules—are configured without scripting. The software implements FDA 21 CFR Part 11-compliant user access control (role-based permissions), electronic signatures for critical operations (e.g., calibration reset), and immutable audit trails for all measurement parameter changes. Bin definitions support Boolean logic across multiple parameters (e.g., “(x > 0.312 AND x 0.325 AND y < 0.338) AND (VF > 3.25 V AND VF < 3.35 V)”), enabling complex multi-dimensional sorting schemes aligned with industry-standard BIN maps (e.g., Cree XLamp, Osram Oslon). Export formats include CSV, XML, and SQLite for integration with MES and SPC platforms.
Applications
- LED wafer-level probing and final test at packaging facilities
- Automated optical-electrical binning for white phosphor-converted LEDs and monochromatic emitters
- Process monitoring of phosphor coating uniformity via correlated color shift under controlled drive currents
- Accelerated life testing (ALT) where simultaneous VF degradation and chromaticity drift must be tracked
- Calibration verification of secondary standards (e.g., reference LEDs) against primary laboratory sources
- Research-grade characterization of novel LED architectures (micro-LEDs, UV-C devices, perovskite LEDs) requiring sub-10-ms transient capture
FAQ
Can the Chame-3000 operate independently without the Chameleon SpectroRadiometer?
Yes—the Chame-3000 functions as a standalone source meter for IV curve tracing, polarity judgment, and parametric pass/fail screening. However, full electro-optical correlation and CIE-based binning require integration with the Chame-LH200 or compatible spectroradiometer.
Is external triggering supported for synchronization with third-party equipment?
Yes—TTL-compatible trigger input/output ports enable hardware-level synchronization with oscilloscopes, pulse generators, or industrial PLCs for custom test sequences.
Does the system support temperature-controlled measurement environments?
The Chame-3000 does not include integrated thermal control, but its software API exposes real-time temperature sensor inputs (via optional external thermocouple module) to condition measurement triggers and apply temperature-compensated bin thresholds.
How is calibration maintained across different electrical modules?
Each SL/SH module ships with individual factory calibration certificates (NIST-traceable). Field recalibration is performed using ZOLIX’s proprietary calibration jig, which validates both voltage sourcing accuracy and current sensing linearity across the full operating range.
What handler protocols are supported for integration with LED sorters?
Standard support includes parallel TTL I/O (up to 16-bin mapping), RS-232 ASCII command sets (compatible with ASM, K&S, and Toray handlers), and Modbus RTU over RS-485 for enterprise-scale deployment.
