New system solution for production tests with LEDs and LED wafers
Instrument Systems presents own current source for LEDs
As a bipolar current and voltage source, the LSM 350 offers all functions necessary for testing LEDs fast. The automatic polarity test feature can be used for single and multi-chip LEDs. Dedicated measurement ranges permit particularly precise testing at low forward currents of 1 μA, and measurement of reverse currents in the nA range. The modular concept includes an option to measure breakdown voltages up to 40 V. Very short settling times reduce the test cycles by up to 40% compared to those of most standard current sources.
The LSM 350 is fully integrated in the LED Tester. This proven turnkey system with the high-precision array spectrometers in the CAS 140CT or CAS 120 series from Instrument Systems allows test routines to be set up with fully automated testing and binning of LEDs and for testing LED wafers. The associated software permits a large number of different functions and evaluation options.
