LED Array Tester Machine | AT100

Maximise accuracy and efficiency in your production with our state-of-the-art LED tester machine. The AT100 Test System runs comprehensive optical and electrical tests, including dim testing and variable optical analysis, ensuring that every LED meets the highest quality standards. The system can process approximately 100 substrates per hour and adapts to your production speed based on the number of LEDs and test requirements. A built-in heating element allows for temperature-dependent tests ranging from 25°C to 100°C, ensuring performance stability across varied conditions.

Flexible input options such as magazines or conveyors, enable the system to function independently or integrate seamlessly into your production line. Its automatic magazine and array ID checks guarantee flawless operation, eliminating the risk of errors. Additionally, the system supports integration with different tester systems, providing a tailored testing experience to fit your needs.

For even more streamlined production, pair your LED tester machine with our PCB loader unloader to optimise handling and efficiency.

Introduction

Dim Test

Optical Test

The AT100 is a fully auto testing machine for Chip-On-Board. It is capable of running dim test, optical test and electrical test. With variable inputs like magazine or conveyor, the system can be run stand-alone or seamlessly integrated into a production line. A wide range of form factors can be tested by switching the probe cards.

The system processes 100 substrates per hour, depending on the number of LEDs on the substrate and the test time.
