Outstanding Benefits of PCB Potting Compound You May Not Be Aware of

Various potting techniques are becoming famous for protecting electronic and electrical components of different types. Such protection is needed to guard the components against shocks, moisture, vibration, extreme temperature, corrosive agents, corrosion ageing, cracking, and others.

This piece will contain several aspects of PCB potting compound, including how they work and their benefits. For instance, it will highlight how potting can enhance performance and increase security and safety for a host of applications. The post will also show how electrical and electronic products can become more competitive due to the right potting techniques. Let’s get started right away!

Why The Need for Improved Protection of Electrical and Electronic Parts?

Almost everything you can find around you these days are powered electronically. Electronics now constitute a significant part of our modern lives. Besides making life easier for users, it is also meant to ensure better services and products.

This is why electronic components must get maximum protection. The use of renewable energy has been the clamor by world leaders. Electrification will assist in cutting down the world’s carbon footprint. In other words, ensuring that electrical and electronic components get maximum protection will help fight global warming.

 

What is Potting?

As we saw initially, the aim of potting is to protect critical and sensitive electronic components from various hazards like harsh climatic and environmental conditions, vibrations, corrosive chemical situations, exposure to fire and heat, and dust.

Potting is completely or partially filling a space with a resin-based material like silicone to provide protection. Encapsulation is a similar technique, except that it requires the electronic or electrical component to be immersed into a mold and affixed to a space.

Having known what potting means, we can go ahead to discuss the benefits in the succeeding section.

 

Benefits of PCB Potting Compound

The following benefits are what potting can guarantee for electrical and electronic components.

 

Heat Resistance

PCB Potting Compound provides improved heat resistance to electrical and electronic components. Potted components can survive heat resistance in different dimensions. For instance, such components are designed to survive extreme temperatures between -50 degrees and 300 degrees.

Potting makes it possible for electronic and electrical components to be used in temperate and hot regions, without compromising the quality of their performance.

 

Flame Retardancy

There is every possibility of a fire outbreak occuring inside an electronic item when in use because of the release of heat as they function.

Potting is preferred for bonding electronic components because of its self-extinguishing properties. If overheating occurs inside the panel, a potted electronic component will not be gutted by fire. It will put out the fire.

Conventional adhesives do not have this benefit. This is one of the advantages of using silicone as a PCB Potting Compound. Just so you know, epoxies and other bonding solutions do not exhibit this same property.

 

Thermal Expansion

Thermal expansion is an important factor in choosing how you bond an electronic component. Silicone has a high thermal expansion rate due to its hardness.

This potting materials does not affect the electronic components that much when it expands and contracts. This property is so important because a potting material that expands without control can actually impact the shape of the finished product; or even damage the item eventually.

Therefore, the heat expansion property of a PCB Potting Compound is more important than you know.

 

Elasticity

The use of a PCB Potting Compound to protect electrical and electronic components is fast becoming a norm in the electronics industry today.

One reason why potting is preferred is because of its elastic nature. Silicone has great elastic features because of how its molecules are structured. This is why potted materials can regain their shape after going through series of expansions and contractions.

 

Impervious to Environmental Hazards

Environmental hazards are real and can affect electrical and electronic components. But you know what? PCB Potting Compound takes protection for electronic components to a whole new level. Silicone literarily does better than any other potting material in this regard.

This characteristic is what makes potting with silicone the best option for electronic component protection in areas prone to harsh temperatures.

 

Vibrations

Manufacturers in the electronic industries factor vibration into whatever they are doing. With PCB Potting Compound, electrical and electronic components get more resistance to vibration.

Silicone is more flexible and softer than other materials, making it ideal for providing the necessary cushion against vibrations.

Designed to endure extreme temperature alterations, silicone provides maximum protection for potting materials. They also offer protection against corrosion.

 

Reparability

Silicone can serve as both a permanent and temporary PCB Potting Compound. That is because it can easily be dissolved if the need arises to repair or rework some of the electronic components.

It can also help the component stay in position for a long time when the component needs no fixing or reworking. So, if you are look at things from both sides of the spectrum, silicone makes a perfect PCB Potting Compound.

 

Dielectric Stability

A PCB Potting Compound like silicone guarantees electrical conductivity and insulation over a specific temperature range. In other words, electronic components potted with silicone can be used effectively over a wide temperature range.

They have insulating properties and conductive properties at the same time. That means the potted component can be a part of the circuit and still not constitute any nuisance to the user.

 

Final Words

Potting techniques have proven to be a game changer in the electronics industry. We learned that potting is a means of offering protection to electrical and electronic components for most devices. Silicone is the chief material used in carrying out potting because of its superior features. We also discussed the benefits of using a PCB Potting Compound to fix electronic components to circuit boards. Silicone can be dissolved from an electronic component if there is need for repair. It is good for both long-term and short-term bonding solutions. As we can see, the benefits are numerous.
