can electronic circuits made waterproof by some insulation?

Question

why the circuits are prone to damage in presence of moisture

Answer 1

Impurities in water lead to oxidation and corrosion of the copper contacts. Since the water is conductive due to impurities, it essentially creates shorts that can damage sensitive components.

Water damages circuitry in much the same way as static electricity. The only difference is that the voltage surges are caused by shorted power supplies and / or capacitors rather than static.

However, if you had perfectly distilled water, it would not conduct. This is why water-cooled computers use distilled water and glycol based coolants. The distilled water doesnt conduct, and the glycol prevents algae and other deteoration.

Answer 2

Yes, electronic circuitrys can be made waterproof. Different applicantions will have different ways to archieve that.
Moisture is a tougher way to prevents. As moisture can gradually get through insulations and affect circuitry.

As previously answered, water and impurities can cause circuitry damages and malfunction due to short circuit.

Some components on the cirucitry has a tendency to absorb moisture and change their characterisitcs. IC can be damaged as moisture accumulate inside the die and then later causing permanent damages.

That's why all IC must be contained and seal with moisture absorbant when they are in storage.

Answer 3

The functionality of the capacitor is storing the electrical energy.it can save and clear the electric charge.current can flow back and froth in a capacitor.In an AC circuit, capacitor reverses its charges as the current alternates and produces a lagging voltage (in other words, capacitor provides leading current in AC circuits and networks) .In a DC Circuit, the capacitor once charged with the applied voltage acts as an open switch.

Answer 4

two main problems with water and electronic circuits:

1) water can conduct electricity so it will cause shorts in the circuit causing improper operation

2) water (and the impurities it may contain) can aid corrosion

Answer 5

Hi. Some are embedded in epoxy and are almost indestructible. They have some in your car.

Answer 6

put plastic coil
