Dust and other contaminants are not fully protected in the PCBA factories of electronic tools. Dirt can easily enter the slots and vents on the housing, and settle on the motherboard. The rotation of fans, especially in large machines, can also blow infected dust onto the printed circuit board.

Vapor Stage Cleaners

The vapor stage cleaning procedure involves boiling any chemical solvent that produces vapor in order to dissolve contaminants that have actually collected on the PCBA.

Compressed Air

Use compressed air in short bursts to blow air directly into the device's open spaces to remove dirt that has accumulated on the surfaces of the gadget, as well as inside the circuits. You can use compressed air when these tiny openings are small.

You will also need a tool to help you clean the board or remove contaminants.

Isopropyl Alcohol

Isopropyl Alcohol is a great tool to clean circuits because it's inexpensive and quickly vaporizes. The beverage also contains fewer chemicals than PCB cleaners. Wear handwear cover when using isopropyl Alcohol, as its high concentration (over 90%) can cause skin damage.

The Use of a Small Paintbrush or Soft-Bristle Brush Is Also Effective

The tiny brush works well to squeeze into the small spaces of PCBs. To avoid damaging the circuit, make sure the bristles are breakable.

Microfiber Towels or Clothing

Towels are a quick way to remove cleaning liquids. If you want to reduce the chance of bits getting stuck in your device, make sure that they are made from microfiber or lint free.

Sodium Bicarbonate

You can use baking soda to remove the deterioration from PCBs. The deterioration of PCBs is due to acid leaks, and salt water exposure. The soda's moderate abrasiveness eliminates deterioration with no adverse effects.

Desk Light, Stove or Hair Dryer

Some of the cleaners listed above can help remove dirt but may also leave behind liquid. To avoid damaging the board, use a warm source to quickly wipe off any liquid. It is important to follow the instructions for how to wipe down the board.

Distilled or Deionized Water

Deionized water is preferred by many people because it does not harm circuit cards. Close your water container when not in use to avoid contamination by dirt and dust particles.
