Metal Monday: Circuit Boards & Their Elements

circuit boardsCircuit boards are a very tricky item and they are not always the easiest thing to figure out so let’s talk about them today. Circuit boards are found in all types of items including: computers, microwaves, laptops, TVs, among many other items. There are many types of metals on and in circuit boards and we want to go over a few of them today.

Common Metals Inside Circuit Boards

Some of the most common metals in/on circuit boards are: Gold, Aluminum, Copper, Silver, and Steel. These items might not always be easily seen, but at least one of them is always on a board to make it work correctly. Gold is one of the best conductors and because of that was traditionally used in all circuit boards. With technologies improving there has been a big change to the metals that are used in circuit boards with aluminum and copper becoming two of the more commonly used metals that are used in circuit boards.

Other Elements of Circuit Boards

When you look at a circuit board sometimes you can see the small gold pins, the aluminum heatsink, or the copper wires that are connected to the circuit boards and that is what makes the circuit boards run the equipment that they are connected to.

Circuit boards are not easy to figure out and we recommend asking your local scrap yard if they buy them and what their different values would be. Gold used to be the metal that everyone was chasing but with new technology like fiber-optic and copper coming out you always have to be aware of what your circuit boards are worth.
