The sector of precise electronics is characterised by the necessity of using the equipment that makes it possible to print out and to automatically apply a micro label in order to identify each small element. Due to the shape of the label production process for marking electronics, they need to be resistant to very high temperatures. Industrial scanners of bar codes or 2D codes, which automatically read the location and the production parameters related to a given component, sometimes complement the process. In HIT-Kody Kreskowe we have implemented many projects for leading electronics manufacturers. Benefit from our experience.
