Compressed Air Dusters: Why Cleaning Your Circuitry Requires a Not-so-Canned Response

Compressed Air Dusters--Why Cleaning Your Circuitry Requires a Not-so-Canned ResponseDid you know dust particles can conduct electricity? Left untreated, they can lead to bad circuit connections and a variety of heat-related issues in your electronic devices. Clearing out dust and debris helps to mitigate these risks and enables technicians to work in a clean environment.

Typically, your first line of defense is a compressed air duster. They are inexpensive and range in pressures to combat varying soil levels. For routine maintenance, an economical choice is Chemtronics’ ES1217, a regular-strength duster that is safe on plastics, nonflammable and also ozone safe. If your system is very dirty, a heavier compressed air spray like Chemtronics’ ES1020 Ultrajet® Duster will do nicely as it’s extra-strong and leaves no residue.

Dust can cake over chips and work its way under components and boards as well. In extreme situations, dust “infestations” will leave a layer of fuzz on your circuit board that must be peeled off before you use a high-pressure duster. Since avoiding dust and debris entirely is unavoidable, it’s best to blast dust particles away before they get carried away.
