Electronics components are everywhere. We use them on daily basis; it’s safe to say that they are an

integral part of our lives. But we should also understand how they wear and stop working due to

corrosion. Many of these electronics failures are directly or indirectly influenced by corrosion. In

various instances breakdown was not consistent and occur because of the surrounding conditions

i.e. (contamination and humidity). In most of the breakdown, water plays a big role which leads to

current leakage hence malfunctioning of the gadget.

Most common types of corrosion failure occur in electronics are electrochemical migration and

galvanic corrosion and various forms of environment influenced corrosion.

Largely used metals and alloys in electronic devices include aluminum, tin, copper, gold, lead, silver

and their alloys.

Intro

Virtually all metallic components in an electronic device are susceptible to corrosion influenced by

humid surroundings especially if aggressive ions are in the surroundings.

Many electronics are coated or protected from external dangers by sealing them inside a capsule but

still, corrosion can break you electronic Electronics. Damaged electronics utilized in industrial

applications need substitution and the loss of production time can be expensive or even pose

security dangers. The costs brought about for this often extraordinarily surpasses the expense of the

damaged electronics parts itself.



An essential matter to take into account is to keep the electronic components properly packed when stored. These components or apparatuses need appropriate packaging to make certain that during lengthened storage they are not damaged. Even the electronic components are vulnerable to mold and corrosion and can get damaged if properly not stored or placed.

Failures caused by severe service life conditions

The exposure of Electronics to situations where humidity, temperature, and environmental hazards,

for example, chlorides, and hydrogen sulfide (H2S), which are not controlled, can result in

environmental corrosion of the metallic parts. With the end goal to limit the danger of corrosion

failure, it is critical to know about corrosion chance amid the design stage, reliability evaluations and

qualifications, assembly processes, storage, shipping, and in the final use of the microelectronic

devices.

On the off chance that service conditions contain H2S or SO2 gas such surface completions can

experience the ill effects of sulfur corrosion if stickiness levels are high. Component corrosion can

occur very quickly in industries such as water treatment, rubber manufacturing, fertilizer production,

or paper mills among others.



Failures in electronic components related to corrosion, can’t be detected effortlessly in the failure analysis that follows. In a number of instance failures take place because of contamination and humidity and are irregular. When any sort of water layer is formed, it causes leakage of currents on the printed circuit board assembly (PCBA). This results in various malfunctions in the electronic component. With the formation of water layer or film, the assembly circuits get corroded. The electronic components are damaged through different types of corrosion out of which Galvanic Corrosion is a major one.

Galvanic Corrosion In Electronics

Electronics almost always have connections between different metals, and even different alloys of

the same metal, which also have different nobilities. Certain parts of electronics, like switches, are so

prone to corrosion that manufacturers have been plating connectors with gold, which is both one of

the best conductors and one of the noblest metals. This is a step in the right direction for

protection of electronics, albeit a somewhat expensive one. But not everything can be gold plated

because of the galvanic reaction between gold and the less noble metals, like silver, copper, and tin,

which make up the bulk of the metal in electronics. Also when the coverage of the plating is not

complete or somehow gets damaged, the ensuing galvanic corrosion is worse than without the gold

because of gold’s exceptionally high nobility.



Galvanic corrosion is a type of corrosion that might render an electronic component useless. This corrosion makes the electrolytes in a liquid draw out adequate copper oxide to sever a trace and prevent supplying electricity to the precise position.

Electronics quite often have connections between various metals, and even unique alloys of a

similar metal, which additionally have diverse properties. Certain parts of Electronics, similar to

switches, are so inclined to corrosion that manufacturers have been plating connectors with gold,

which is both extraordinary compared to other mediums and a standout amongst the most

respectable metals. This is a positive development for the protection of Electronics, but a fairly costly one. Yet, not all things can be gold plated in view of the galvanic response among gold and the less classed metals, similar to silver, copper, and tin, which make up the majority of the metal in

Electronics. Likewise when the inclusion of the plating isn’t finished, or some way or another gets

damaged, the following galvanic corrosion is worse than without the gold due to gold’s

especially high corrosion prevention properties.

Electronic devices can fail due to a number of failure modes depending on inherent factors related

to PCBA materials, design, and cleanliness under exposure to humidity and other gaseous

conditions. Some failures can be avoided by simple remedial measures such as changes in materials,

the slight change in PCBA design, and optimal PCBA cleanliness.

How rust inhibitor can protect your electronics and save you millions:

What rust inhibitor solution truly does is that, it makes an impermeable layer that prevent

humidity and oxygen from reaching metal surfaces; without that collaboration, rust doesn’t form.

Something else it is known to do is it decrease the rate of corrosion since it has the chemical solution

that prevent oxygen and humidity from consuming any metal it comes into contact with.



Any electronic component when gets wet, corrosion starts then and there only and leads to failure of the component. But, every kind of liquid doesn’t impacts in the same way after getting exposed upon the electronics. Unadulterated water doesn’t have the electrolytes that would damage any electronic device. It is the other form of liquids that cause bigger threats, such as soda or carbonated drinks etc. These forms of liquids possess minerals of higher level which are able to conduct electricity. In short, the more our electronic components stumble upon adulterated water, we face further causes to be bothered.

Rust inhibitor Solutions have been trending as the years progressed; along these lines, in addition

to the fact that they adhere securely to metal surfaces, they are anything but difficult to apply so

they can be utilized on various metal finishes— car, train, trestles, or scaffolds. It’s additionally

worth referencing that rust paint never requires an activator or impetus for expanded

effectiveness in preventing corrosion, which means no exceptional planning or strategies are

required with the end goal to utilize it legitimately. Also, since it’s anything but difficult to apply,

you needn’t bother with an expert to paint it over anything that you wish to avoid corrosion for.

You can utilize a run of the mill paintbrush, roller or sprayer to apply rust paint appropriately.



As electronic components are being increasingly used in today’s world, where environmental contamination has reached to a significant level, the need to protect the electronics is gradually rising.

The most imperative benefit of utilizing rust inhibitor solution is that it can spare you a ton of cash

for repairs, and replacements. Rust is such a problem to manage; it stains and makes a dull

appearance, and in the meantime, it damages the structural integrity of steel parts. This is the

reason rusty electronic parts don’t have a high resale cost; in addition to the fact that they are

terrible, it truly takes a great deal of cash to turn around the effect of rust on a heavy machine. Rust

or corrosion makes a pointless money outflow; in this manner, on the off chance that you can keep it

from happening with the assistance of rust inhibitor solution, for example, Rust Bullet, you just have

everything to pick up from it.
