An automatic line for smoke sensors assembling arrived to the Romanian customer. Due to the coronavirus situation, part of the line was installed remotely, thanks to the possibility of using Mainware smart maintenance. The line consists of a total of 4 modules. The components are first equipped with PCB LEDs and a thermistor. Then follows the soldering station and first tester. The second module contains a parts storage, where the individual parts dry. In the third module, the entire product is completed and continues to the second tester. From there, the product is moved to the fourth module, where it is packed in a box along with a paper manual.
