I know what you’re thinking: “He can’t possibly write an entire article dedicated to the use of copper in PCBs.” I say, “Hold my beer.”
Copper is the primary metal for standard PCBs, which you can find in pretty much every type of electronic device on the planet. And while standard PCB capabilities depend on what materials are used and how they are constructed, copper is the go-to choice.
Copper works very well for the conduction of electrical current in any environment. In fact, it has the highest electrical conductivity rating of all non-precious metals, making it highly effective for performance and cost. For a vast majority of PCB designs, copper is the conductor of choice. Copper conducts the signal and power for just about every electronic item in your life.
Way to go, copper! You are doing a great job. Keep it up.
