40 Diversity in LED assembly SEROhasmanaged to develop special skills in this field of technology. PCBs assembled with LEDs for reverse lights, turn signals, brake lights, daytime driving lights, as well as interior lighting are produced every day in the state-of-the-art and fully automatic electronic manufacturing plant in Rohr- bach (Rhineland-Palatinate) for big players in the automotive industry. Depending on customer requirements, the LEDs shine with different intensities and colours, and are assembled onto classic green as well as white, red, or black PCBs. This variation in colour reliably prevents distortion of the light colour and ensures optimal results. RGB LEDs have become particularly pop- ular in vehicle interiors, as they can take on any kind of colour tone. Drivers can ex- press their personality through the light strips within the interior of the vehicle. The challenges in production During the assembly process, however, the small lights can lead to quite a few chal- lenges. To date, it is not yet possible to de- fine the binning of LEDs in advance during production. In LED jargon, binning refers to the categorisation of LEDs into various light classes. This usually takes place depending on the luminosity, colour temperature, volt- age, and tone of colour. When looking at the production process of SERO, this means that the assembly of one and the same product needs to be adjusted continuously, with LEDs supplied in a binned manner. SERO’s proprietary production planning system modifies the assembly of the com- ponent in a fully automatic manner as soon as the LED binning has been registered and checks the stock of required components. All information is then automatically trans- mitted to the SMD assembly lines and test- ing lines. The functionality, intensity, and tone of colour are then measured during the electronic testing and compared with the available requirements. This is how SERO guarantees uniform quality of light, in spite of different binnings. And the results are impressive: SERO uses the latest in LED technology to help repu- table automotive brands bring light into the darkness! https://sero.de/en www.facebook.com/leaderinems SERO brings light into the darkness The latest in LED technology for the automotive industry By Jasmin Korbus, Marketing Manager, SERO GmbH The rise of LED lighting is not merely limited to our homes. More and more LEDs are being used in the auto- motive industry as well, offering the end user benefits over conventional lights, such as longer service life and greater energy efficiency. However, therearegreat challenges thatmust bemastered in theproductionprocess to guarantee that, in the end, every light shines in the sameway. Existing platformdesigns and vehicle architec- tures are being turned upside down in this regard to achieve improvements in the mobility of tomorrow.
