In this paper we propose an augmented reality (AR) based assistance system for reliably teaching the assembly process of printed circuit boards (PCB) to workers by using a smart glass running a self-developed software. The system is operated freehand by looking at QR-Codes and highlights a component's retrieval location and installation point in the user's field of vision by using four markers. A study executed in a production line of an Electronics Manufacturing Services (EMS)-company resulted in an errorless performance of each individual participant who was equipped with the system. This paper describes the related work, concept and implementation of the software as well as the conducted study and its results. Finally a conclusion summarizes the success of the system and hints at future work.
