LED Production Test Using the B2900A Series of SMUs

PublishTime：2021-04-29

Numerous emerging light emitting diode (LED) applications have created a demand for LEDs with higher quality and reliability. Testing that is both more accurate and faster and that permits quicker sorting is therefore required for both on-wafer devices during fabrication and for packaged devices during final test.
Both electrical and optical tests are typically performed on LEDs. The Keysight Technologies, Inc. B2901/02/11/12A Precision Source/Measure Unit is the best solution for all electric tests such as a forward voltage test (V-F), a leakage current test (IR) and a breakdown voltage test (V-BR). In addition, it can be used to provide forward current bias during optical test.
The B2900A Series of SMUs is a compact and cost-effective benchtop Source/Measure Unit (SMU) with the capability to source and measure both voltage and current. They cover currents from 10 fA to 3 A (DC)/10.5 A (pulse) and voltages from 100 nV to 210 V. In addition to these comprehensive measurement capabilities, the B2900A Series of SMUs possesses high throughput that reduces test times. The B2900A Series of SMUs also has many features that make it well-adapted for production test, such as pass/fail binning, a digital I/O interface for handler control, and code compatibility with standard single and dual channel SMU products.
This technical overview focuses on the electrical testing of LEDs in production. If you need to perform optical tests in addition to electric tests, then dual-channel models of the B2900A Series of SMUs can be used. The dual-channel models of the B2900A Series of SMUs permit one channel to measure photo diode current while the other channel drives the LED.
