Printed Circuit Boards
“What is the casing for modern electrical systems?”
Primitive electrical systems are connected through a dangerous process of point to point wiring. However, how could we improve and replace this framework? Well, let’s start with the basics. First, let’s obtain a base material called a substrate to act as the base unit. Then, let’s put copper wiring on both sides of the substrate. Afterward, let’s apply a solder mask to prevent the substrate from interacting with other electrically conductive parts. Finally, let’s imprint a silkscreen so people can easily identify all of the components of the system. This device is known as a printed circuit board, and is the fundamental framework for all modern electrical systems!
