Efficient multiple testing of LEDs
2022-05-24
The colorCONTROL MFA-7 LED Analyzer precisely and efficiently checks the correct color, intensity and function of LEDs. The sensor can monitor up to 28 measuring points simultaneously. Each measuring point is freely configurable. The sensor offers a data rate of 100 Hz with a dynamic range of 1 to 50,000 lx. The repeatability is also significantly increased with xy ˂ ±0.000025 compared to previous models.
The measuring system stands out due to its application flexibility. You can position the MFS receiver sensors anywhere in relation to the test object and adapt it to the respective measurement task. High-quality receiver sensors with plastic fiber optics for different working distances and measuring spot sizes are available. Lengths and temperature ranges are also variable.
The free sensorTOOL software is used to parameterize the LED Analyzer. The software also reads out and records the measured values for all measuring points synchronously. The integrated RS422 interface allows easy connection to process control units. Furthermore, the MFA-7 series has USB and RS232 interfaces.
Application in the electronics industry
The colorCONTROL MFA-7 LED test systems are used, among other things, in the electronics industry for quality control of PCBs during in-circuit test (ICT) in the clean room. The sensors are positioned precisely above the LEDs at a distance of approx. 1 mm. Due to their compact design, the receiver sensors can be integrated between test needles or test pins, which are fixed in the cover of the test adapter.
The great advantage of the colorCONTROL MFA-7 multi-point color recognition systems from Micro-Epsilon lies in the inspection of different measuring positions that are spatially far apart. A small sensor head and thin optical fibers enable use in confined spaces.
