Robert, Mitch and me visited a plant in Centurion, near Pretoria, where PCB prototypes have been manufactured for our work with the Prometeo system at CERN. So far we are happy with the interaction and the quality of the PCBs. We will continue working with them. The visit was very instructive in terms of how the process of manufacturing PCBs works and what are the different steps involved in it. It was also very useful in terms of understanding the capabilities and limitations.
