The challenges of joining small components, such as the housing of the UV sensor of the "Sun-a-wear system", are complex and wide-ranging. However, by using the right joining process, requirements like - protection of sensitive electronics from dirt, vibrations and external pressure during and after joining - durable and materially bonded connection of the two housing parts, which is reliably watertight - filigree joining zone due to the size of the sensor, which requires very precise joining of the components without damaging the electronics are solvable and reproducible. The laser plastic welding process easily fulfills these requirements mentioned here. There is no vibration, mechanical stress, dust or dirt formation during the welding process. In addition, it is reproducible thanks to 100% repeatable welding parameters and meets the high quality requirements, such as watertightness (IP69), which must be guaranteed. The "Sun-a-wear system" enables the user to monitor and measure UV radiation using a small sensor, which is carried on the body and sends the data to the connected app. With a size of 10 x 17 x 37 mm and a weight of 9 g, it is almost invisible.     #laserplasticwelding #innovation #automotive #medicaldevices #technology #manufacturing #teamevosys #skincare #healthcare #skinprotection Evosys Laser Services GmbH
