Feb 1, 2018: Prüftechnik Schneider & Koch has expanded the LED inspection range of its LaserVision LED AOI system with a reel-to-reel option. The system can test different LED ribbons with differently placed LEDs on a single roll, but also separate ribbons on different rolls to be simultaneously inspected.
With the test system LaserVision LED, LED modules in the production line can be 100% tested in series production. This includes both the AOI test and the complete electrical test, as well as the combination resulting in the optical parameters of the operated LED . Thus, a 100% test in inline process step can be achieved.
Including all components, LED assemblies can be automatically checked for assembly, solder joints, short circuits, polarities, etc. In addition, under voltage photometric tests are possible. The unique combination of photometric measurement and camera inspection under line tact conditions is used. LED luminaires can be completely tested as end products and / or in different production stages. The test is carried out for each individual LED . The system can also be used as a pure AOI system.
The electrical contacting in inline mode via a parallel with servomotors driven contacting, which can be designed both from below and from above. The special feature is the exemption of the optically inspected areas. For this purpose, especially a hold-down mechanism has been developed.
