With more and more people using technological devices every day, the need for electromagnetic interference shielding to protect sensitive devices is increasing drastically. Electromagnetic interference is a kind of disturbance that can cause damage or performance degradation in electronic equipment. The interference could be either man-made or natural, but in both cases, it can put your sensitive and expensive electrical devices out of order. Apart from the Faraday cage and the board level shielding, experts also count upon special shielding coating solutions to offer the ‘protection’ that a device needs.
How Can Coating Help?
Your high service CPUs, devices and appliances can start to show performance issues due to EMI exposure. With expert assistance you can coat the outer layer of devices or appliances with EMI shielding solutions to divert or deflect the EMI radiation. Coating solutions can be applied manually or mechanically on targeted items by experts. These coatings are designed to offer adhesion facilities to different type of substrates.
Following are some of the qualities of these solutions:
- They come with great abrasion resistance
- They can keep the coated surface completely leveled
- General spray paint equipment can be used for application
- The coating works well with electrical connectivity choices
It is obvious that with these benefits, EMI shielding coating solutions can easily protect expensive and sensitive devices or appliances from EMI interferences.
What are the Materials Used for EMI Shielding Coating?
Copper, aluminum, zinc, and tin are the primary metal alloys used in developing the coating solutions. The coated area can absorb or reflect EMI and protect the electrical circuitry from electrical noise. Nickel and silver can also offer protection against EMI. Therefore, some coating solutions even come with nickel, silver copper, and pure silver metal mixtures. As each combination has a unique reaction and performance level, you should compare the materials when selecting the coating products. You can even ask experts to help you find the right coating solution that can satisfy your EMI shielding requirements best.
Application Details of EMI Shielding Coating
Selecting coating solutions as shields against EMI can offer you the most economical choice for protecting your electronic devices or equipment. High conductivity is one of the primary benefits of using these solutions. Plus, these coatings offer adhesion and great durability. Therefore, once you have applied it, you do not have to be afraid about losing your electrical devices to the EMI any time soon. Coatings can be applied on:
- Medical devices
- Office equipment
- Industrial equipment
- Cell phones
- Consumer electronics
- Military devices
You can use these coating solutions for painting narrow lines in flat or three-dimensional surfaces. Materials of these coating solutions make them fairly flexible to satisfy various usage requirements. It is spray-able and can be used in coating plastic housings.
Check the Compatibility before Buying
Checking the compatibility is important when you have decided to use coating solutions for your requirements. Whether it is a small electrical gadget with plastic cover that you want to coat, or want to turn your room into an EMI-free workspace, you need compatibility information to make the smart purchase decision. Since various coating solutions come with a combination of materials, they offer different level of adhesion to various surfaces. In such cases, knowing which product would be right for you, can help you make the right choice.
In today’s world, electronic interference shielding has become mandatory. This has inspired the shielding solution providers to come up with new and innovative products in order to rise up to the challenge posed by the modern EMI-enveloped world. Conductive paint has also emerged as a reliable option that is used when one needs to apply a conductive surface coating on things such as plastics.
