Electronic devices and systems that are used in critical applications are usually disrupted by electromagnetic waves. These applications are core in military, aerospace, and medical electronics, industrially based touch screens, massive transit systems as well as vehicular control systems. This wave causes a series of threats to such applications thus calling a need for the respective engineers to incorporate EMI seals in electronic devices.
The intensity of interference spans from temporary loss of data to unbearable circumstances like the entire system failure and even loss of human life. This presses the engineers in the faculty on their toes so as to ingrain a deeper understanding of the EME in their application environments. This paves the way for them to develop protective sealing materials that can tolerate all intensities of electromagnetic fields with high RF that can cause interference to wireless communications.
The interference are sourced from two main categories, namely; ambient and power quality problems sources. The former can be triggered by both man-made and naturalistic sources that may include; computer circuitry systems, arc welders, lightning, magnetic field flux among many others. Additionally, interference emanating from power quality problems include conditions like voltage sags and spikes, electrical noise on the mains power lines and EFT. This poses a threat to critical infrastructures.
The seals are useful in that they take the front-line in compacting the adverse effects triggered by EMI in electric systems. This is usually crowned by the electromagnetic shielding process which entails obstructing electromagnetic radiations induced by electrical circuit systems conveying vigorously changing signals. These signals may cause interference or noise. This is solely achieved by having a distinct separation of these circuits with an insulating barrier that is also conductive.
The electronic warfare in military assets and other critical infrastructure include; the high-altitude electromagnetic pulse, high-power microwave weapons, E-bombs among others. This has necessitated the designers to carefully assess such threats in order to incorporate appropriate protection shielding seals in their gasket designs. The shielding gaskets are mechanical devices that aid in protecting electronics from EMI.
Anciently, the shielding was achieved via fabrication of metallic components to structure sealing materials that take the shapes and fit the electronic enclosures. Nevertheless, they were associated with a drawback of deforming thereby leaking EMI into the circuits. In the present day, the developers are using more innovative shielding materials like metallic wires and foams.
Uniquely, most of the manufacturers use particle-filled silicone EMI sealing. This is because they are the most excellent choices for ruggedized touchscreens since they usually attenuate electromagnetic emissions. They also provide electrical conductivity as well as ensuring environmental sealing in fettle that range from desert heat to arctic cold. These types of seals also cushion the device from mechanical shock.
Thus, the seals are of paramount importance in special types of industrial applications in fields of military, medical, vehicular control systems and mass data transit. Their incorporation in such fields have aided in alleviating the electromagnetic interference in critical applications. Innovations have also played a major role in developing effective sealing elastomers that satisfy an array of shielding requirements.
