Ultrasonic PCB Cleaner-How To Use It

Just like any other component, PCBs get dirty and require regular cleaning. Using distilled water may work well, but if the process is not well done, it can lead to many problems. Also, using stronger solvents like acetone may ruin your PCBs. When you choose to use acetone ultrasonic PCB cleaner, ultrasonic vibration atomizes acetone, making the PCB soft. However, the use of detergents and distilled water can help you do a great job.

1.Ultrasonic Cleaner for PCB

When the PCBs used in our domestic equipment such as cell phones get dusty and dirty, they need to be cleaned immediately. If left uncleaned, they are likely to deteriorate and may not provide the required service. Consequently, it would help if you found an appropriate way to clean your PCBs. If you have no idea about how ultrasonic cleaning works, it will be necessary that you partner with a company that provides ultrasonic PCB cleaning services.

Notice that the cleaning of PCBs is a delicate process that requires utmost care to avoid damaging, loosening, or compromising the components used. It means that you must take some care when selecting the cleaning method to use. There are a few potholes that need to be avoided when doing this.

• Avoid using contaminants that may accumulate on your PCB by ensuring that they are removed before they cause problems.

• Do not allow the accumulation of dust and dirt on your PCB by using a smooth brush to dust it off gently.

How to Clean the Dirt

Using a brush can effectively remove the dust. Unfortunately, there is always a limitation to what the meeting can remove and where it can reach. This is where the use of compressed air comes in. It has the advantage of getting many areas, but care must be taken since it can damage vital connections. You may also opt to use specially designed vacuum cleaners to remove dirt and dust from your PCBs.

This is a cleaning machine that uses high frequency to cause cavitation and results in the implosion of billions of bubbles in solutions in the tank. The transducer creates these bubbles at the bed of your tank, and when they blast contaminants, they clean the surface. Ultrasonic creates sound waves with high frequencies of about 20 kHz that lead to cavitation hence the cleaning process.

This technique is not used much because it can loosen connections or cause damage to the components. The method can also cause separation of the features and damage the bond wire pads of the devices, even though this is the most preferred cleaning method capable of reaching the most difficult parts of your component. It is also the quickest method of cleaning components.

Cavitation can be used to remove gross contaminants because it creates high temperatures and pressure over 10,000PSI. When FR4 PCBs are NEMA grade designated material for glass-reinforced laminate material. They are made of woven fiberglass with an epoxy resin binder. Moreover, they have high frequency used; it creates smaller bubbles which clean gently and can penetrate the crevices and cracks and blind holes.

4.Ultrasonic Cleaner PCB Board

It is true that dirt and dust could affect printed circuit boards used in electronic devices such as cell phones and other commercial and domestic appliances. It, therefore, requires Gadgets such as electronic ultrasonic cleaners to help clean the delicate parts. The devices can also be used to clean complex PCB boards safely and efficiently. Ultrasonic cleaning is an advanced and innovative technique that uses technology for offering cleaning services that were initially thought to be complicated.

The technology has been around for a while now and finds many applications in military and medical areas. It uses ultrasonic technology to help clean surfaces faster. Considered excellent when it comes to cleaning PCBs because:

  • It allows you to clean your gadgets fast
  • Components that are cleaned using this method become more reliable and efficient
  • It can be used to clean components with blind holes
  • It is the safest way to help you remove contaminants without exposing your component to damage.

How It Works

It works through cavitation, where microscopic bubbles are formed and forced to fall violently on the surface to be cleaned. By doing so, it helps to remove dirt and dust. Immersing the PCB in a tank filled with a cleaning solution is allowed, but it must be adequately dried for a safe outcome.

Ultrasonic cleaning of devices should take 15 minutes and help you save a lot of money and time. It also ensures that your electronic parts are protected and eliminates any possible damage to your PCBs.  

5.PCB Ultrasonic Cleaner Solution

There is plenty of ultrasonic cleaner solutions to choose from. Some of them are designed to remove flux and deposits on PCBs.

The answers come in concentrated form but could be added to water to dilute them before they are used. When used, they help to remove contaminants and do not corrode or damage metal components. Most of the solutions are safe on copper, brass, aluminum, and other metals. It is recommended that you test the solution before using them.


Cleaning PCBs using ultrasonic cleaners has become common because it is the only way to help preserve PCBs and electronic devices. PCB Ultrasonic Cleaner Solution is a reliable cleaning option and guarantees that your PCB remains clean and in good working condition throughout. It helps to clean sensitive and complex parts of your PCB. It means that PCB cleaning need not be a daunting task and should be used to ensure that our components remain clean.
