How To Identify Electronic Components On A Circuit Board

By | October 14, 2021



Having a basic understanding of how to identify electronic components on a circuit board is an invaluable skill for any electronics enthusiast. Knowing how to identify components and what they do can save you time, money, and frustration down the line.

Navigating all of the components on a circuit board can be overwhelming for novice electronic engineers. After all, each component has a unique purpose and purposeful placement. Fortunately, there are some simple tricks and techniques which can help you to quickly and effectively identify the various parts on a circuit board.

The first step in identifying components is to understand the symbols printed on the board itself. These symbols represent the different components that make up the circuit board. Common symbols include resistors, transistors, capacitors, and inductors. Once you’ve become familiar with the symbols, you’ll be able to more easily identify components and their functions.

The next step is to use a multimeter to check for current flow. Connect the multimeter leads to two contact points on the board and see if current is flowing. If it is, this will help you determine the type of component that exists on the board. Make sure that you always check the voltage as well, as this can help indicate whether the component is a resistor or inductor.

Another useful tool in identifying components is a microscope. Using a microscope, you can look at the pins of the components and compare them to their counterparts on the board. This can be especially helpful when trying to figure out what type of component it is. You can also use a multimeter to check if the pins are live.

Finally, once you’ve identified the components on the board, take a look at the connections between them. Are they connected in series or parallel? Do they have voltage drops across them? This can help you determine the function and purpose of each component on the board.

Now that you know the basics of how to identify electronic components on a circuit board, you’ll be better equipped to troubleshoot and repair electronic circuits. Knowing what components are present and how they interact with one another can give you a greater insight into the inner workings of the board. So don’t be afraid to get your hands dirty - start experimenting today and you’ll be well on your way to becoming an expert!
