Cleaning your printed circuit boards (PCBs) is important to keep them working well.

Here’s how you can do it easily:

1.Check Your PCB: Look for any dirt, dust, or sticky stuff on your PCB. This will help you decide how to clean it.

2.Choose Your Cleaning Method: If it’s just a little dirty, you can clean it by hand. If it’s very dirty, you might want to use an ultrasonic cleaner.

3.Make Your Cleaning Solution: If you’re cleaning by hand, mix some IPA or electronic cleaner with water.

4.Clean the PCB:

By Hand:
Dip the brush in your cleaning solution.
Gently scrub the PCB and components to remove dirt and grime.
Use a cloth or paper towel to wipe away any excess liquid.

By Ultrasonic Cleaner:
Put your PCB in the cleaner with the cleaning solution.
Turn it on and let it clean for a while.
Take out the PCB and rinse it with water. Then dry it well.

5.Check Your Work: Look at the PCB closely to make sure it’s clean. Use a magnifying glass if you have one.

6.Dry Your PCB: Let your PCB dry completely before you use it again. You can use compressed air or an air blower to speed up the process.

By following these steps, you can make sure your PCBs stay clean and work for a long time. Remember to stay safe by wearing goggles and gloves when handling cleaning chemicals.
