Isopropyl alcohol is a great PCB cleaner because it is inexpensive and evaporates quickly. Baking soda is most effective when treating corrosion, as it dissolves the troubled area and neutralizes the acidic qualities of the residue. It possesses mild abrasive qualities that excel in removing corrosion or residue that will otherwise not come off with simpler means such as a brush and distilled water. If you’re not satisfied with the dust removed, open the device with a screwdriver and work your way around the components, carefully cleaning the circuitry with the air.īaking soda, or sodium bicarbonate, is an effective means of removing grime with minimal risk of damaging the board. Use short bursts to spray the air inside the ventilation ports.

Disconnect the device from its power sourceĭisassembling hardware can be hazardous for the electronics, so make sure you understand how to properly handle the devices you work with and how to reassemble them back to their functioning state.Get in the habit of ensuring any electronics not in use are set to the “OFF” position, as the likelihood of adverse repercussions resulting from water damage significantly drop if the affected areas dry before reactivation.Įxercise caution when handling circuit boards: To avoid dirty circuit boards, you can take preventative steps. Get PCB Replacements Prevention and Safety With Circuit Boards This harms a circuit and damages your device. Once a liquid with good conductive qualities contacts an active device, electrical connections travel through currents to deactivated regions of the circuit board that can lead to short-circuiting. Even plain drinking water contains ions such as sodium chloride and a slew of other minerals that heighten its reaction to electronic devices. The build-up of unwanted material leads to overheating and component failure.Ī liquid such as water is not nearly as detrimental to electronics as the additives it almost always contains.
The fans responsible for keeping equipment’s temperature at a cool environment suitable for proper functionality can draw in debris found in the air and any dirt clinging to nearby surfaces. Over time, water, dust and grime can find their way into your company’s devices and build up to a point where you must take action to prevent permanent damage to the equipment.
Request PCB Repair Quote How Do Circuit Boards Get Dirty?Ĭircuit boards are found in nearly all electrical devices, including computers and industrial equipment. Read on to learn how to clean your circuit boards while also maintaining your own safety standards. Watching out for such dangers and addressing the damage they cause can keep your work productive and the tools needed for the job functioning properly. A slew of different materials are hazardous to the performance and safety of these devices. Cleaning a circuit board can seem like a difficult task to tackle, but these boards get dirty all the time.
