COC Testers are automated testing systems designed specifically for Chip-on-Carrier devices, offering high-throughput, precision testing and quality assurance. They are critical in ensuring thermal stability, optoelectronic performance, and overall reliability in high-performance semiconductor devices.
Technology and Functional Architecture
Core Capabilities
COC Testers are engineered with dual-platform designs that minimize loading/unloading times and temperature-control wait periods, supporting continuous automated operation. Key features include:
- Auto-loading and unloading compatible with fishbone fixtures.
- TEC-based temperature control spanning 20–100°C for precise thermal management.
- Comprehensive testing capabilities, including LIV (Light-Current-Voltage) analysis, spectral measurements, and backlight power testing.
This enables full functional validation and screening of CoC chips, meeting the high reliability and precision standards demanded by optoelectronic, power, and RF industries.
Supply Chain Dynamics
The upstream supply chain includes semiconductor wafers, ceramic or metal substrates, bonding wires, and optical adhesives, coupled with critical components such as TEC cooling modules, spectrometers, power meters, photodetectors, and automated handling units. This integrated supply chain ensures system reliability, repeatable measurements, and high automation efficiency.
The midstream consists of COC Tester manufacturers and integrators specializing in full-automatic and semi-automatic systems. Downstream, the equipment is deployed by optoelectronic manufacturers, power device producers, RF/microwave component manufacturers, and new energy vehicle electronics suppliers.
