Are you interested in making your own printed circuit boards (PCB)? Perhaps you have thought about the possibility of someone reverse engineering your design once your PCB is manufactured. Reverse engineering is the act of closely examining, decomposing, or taking apart your product to either extract valuable information regarding your engineering and design efforts or simply be able to reproduce your design without having access to any of the source files. In other words, someone can knock off your design if you are not careful.
