I often work with circuit boards at my job. I don’t do anything special, I mainly just clean them and screw them into their housings. But when we clean them, we completely soak them into alcohol over and over again until they are spotless. How does this not damage the circuit board or the components on the board? Yet if I drop my phone in water, it will ruin it.
In: Chemistry
The reason behind it is the difference in the property of the liquid.
Water and it’s molecules have the property to conduct electricity due to a “plus and minus pole”, whereas high grade alcohol is non conductive (the molecule structure doesn’t allow for pole formation).
Additionally water is corrosive to most metals, meaning that a lot of metals will form oxides (iron & rust or copper & the green patina) which do not have original pure metal structure and property.
Alcohol (high grade/percentage) on the other hand has the ability to degrease due to the simular structure to fats.
