LED Test & Automation Instruments


The LED industry has grown as a result of greater interest in energy savings and environmental protection. The production process of an LED module starts from Epitaxy (EPI) to Chip Process and then ends with Package. Different LED products are designed to meet the diversified requirements of various industries such as mobile phones, vehicle lamps, and LCD backlights.

Chroma's LED test equipment can be applied to die saw and expansion prior or subsequent for electricity, optics, and electrostatic discharge (ESD) tests. With the user interface integrated prober it can inspect the LED rapidly. For package phase, it can perform electrostatic discharge, thermal resistance and tri-temperature tests to simulate the environment changes in temperature and humidity for measuring the electrical and optical characteristics of LED. Furthermore, it can perform life cycle tests on LED Flash Light, LED Light Bar and OLED for LED modules. This solution also provides various customized LED electrical and optical test equipment for diverse test applications.
