Electronic boards are found in almost all electrical devices, including computers and industrial equipment. Over time, water, dust and dirt can enter the devices and cause damage to the equipment. To avoid this, the boards must be cleaned regularly.
Depending on the type of substance trapped on the electronic board, various tools can be used:
Compressed air;
Baking soda;
Isopropyl alcohol;
Distilled water;
Household detergents;
Soft brush and lint-free fabric.
How to clean the board:
Completely disassemble the device. Disconnect all cables and open connectors and remove the screens to gain full access. Place the board in an appropriately sized vessel with enough isopropyl alcohol of 90% or higher to immerse it completely.
After you have removed the device from the cleaning solution, use a soft-bristled tool such as a toothbrush or brush to remove any remaining dirt. Be careful not to clean vigorously, so as not to damage the board.
After you finish cleaning, place the board under a hair dryer installed in the cold, or under a table lamp to completely dry the remaining moisture from the detergent solution.
Check your board for any signs of liquid that could damage it and check if there is any damage.
Assemble the device and check if it is working correctly. The battery, LCD display and logic board are the most common components that fail when exposed to liquid, so study them first.
At the moment, there are a large number of different washing liquids, but in order to choose the right one for you, you need to understand the capabilities of your existing or purchased equipment and the required surface cleanliness.
