Mae PCB glân yn bwysig ar gyfer dibynadwyedd. Bwrdd cylched printiedig may sometimes accumulate dust or other contaminants and need to be cleaned. A dirty PCB may affect the proper function of its intended design. Whether your board is dirty due to exposure to its working environment, or because its packaging or protection is not properly protected, it is important to perform proper cleaning methods to improve reliability.

Sut mae PCB budr yn effeithio ar swyddogaeth

Dust consists of materials suspended in the air. It is complex in nature and usually consists of a mixture of inorganic mineral materials, water-soluble salts, organic materials and a small amount of water.

As SMT components become smaller and miniaturized, the risk of failure due to contaminants increases. Mae astudiaethau wedi dangos yn glir bod llwch yn gwneud byrddau cylched yn fwy agored i fethiannau sy’n gysylltiedig â lleithder, megis colli ymwrthedd inswleiddio wyneb, ymfudo electrocemegol, a chorydiad.

How to clean PCB

Extra care should be taken when cleaning PCB. Dylid ystyried rhagofalon ADC a dylid eu datgysylltu a’u perfformio mewn man sych. If you use incorrect cleaning methods or procedures, the board may not work at all.

Glanhewch y llwch

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

Fflwcs glân

Circuit boards with residual flux AIDS must be cleaned with saponifying agent. For amateurs and engineers, it’s most common to wipe wine. Gellir brwsio brws dannedd ag alcohol a gellir ei ddefnyddio i brysgwydd unrhyw fflwcs. Sylwch, os nad oes fflwcs golchi llestri ar eich weldio bwrdd, bydd yn anodd ei dynnu ac efallai y bydd angen glanhawr cryfach.

Clean the corrosion

Defnyddiwch soda pobi i lanhau mân gyrydiad a achosir gan fatris ac eitemau eraill. It can be used to remove dirt without damaging the board. Mae soda pobi ychydig yn sgraffiniol ac yn helpu i gael gwared â chorydiad neu weddillion a fyddai fel arall yn amhosibl gydag offer syml fel brwsh â dŵr distyll. It also neutralizes the acidity of the residue.
