Clean PCBs are important for reliability. The printed circuit board may sometimes accumulate dust or other contaminants and need to be cleaned. Dirty PCBs may affect the normal function of their intended design. Whether your circuit board is dirty due to exposure to its working environment or due to improper packaging or protection, you must take appropriate cleaning methods to improve reliability.


How Dirty PCBs Affect Functions

Dust consists of materials suspended in the air. It has complex properties and usually contains a mixture of inorganic mineral materials, water-soluble salts, organic materials and a SMAll amount of water.


PCB assembly


As SMT components become smaller and smaller, the risk of failure due to contaminants increases. Research has clearly demonstrated that dust makes circuit boards more vulnerable to moisture related failures, such as loss of surface insulation resistance, electrochEMIcal migration and corrosion. PCB assembly and pcb design factory explain that clean PCB is very important for reliability. The printed circuit board may sometimes accumulate dust or other contaminants and need to be cleaned.


How to clean PCB

Take extra care when cleaning PCB. ESD precautions should be considered, which should be disconnected from the power supply and carried out in a dry place. If incorrect methods or steps are used for cleaning, the circuit board may not work at all.


Clean dust

For dust, the best way to remove dust is to blow the circuit board clean with compressed air. Be careful of sensitive areas that may cause damage. Toothbrush is another tool that you can use to remove dirt and dust.


Cleaning flux

The circuit board with residual flux must be cleaned with saponifying agent. For amateurs and engineers, the most common is wiping wine. The toothbrush can be wetted with alcohol and can be used to scrub any flux. Please note that if your circuit board is welded with cleaning free flux, it will be difficult to remove, and you may need to use a stronger cleaner.


Clean corrosion

Use baking soda to clean the slight corrosion caused by batteries or other items. It can be used to remove dirt without damaging the board. Sodium bicarbonate has mild abrasiveness, which helps to remove corrosion or residues. Otherwise, using simple tools (such as a brush with distilLED water) will not produce corrosion or residues. It can also neutralize the acidity of the residue. PCB assembly and PCB design factory explain that clean PCB is very important for reliability.
