Conformal Coating vs. Encapsulation - Protecting Electronic Devices, Which Do I Choose?

Dodatki: Conformal Coatings, Encapsulation Resins

The electronics industry is one of the most rapidly expanding industries to date, with new applications seemingly endless. Printed circuit boards (PCBs) are found in many domestic, industrial, automotive and military devices, to name but a few. In such applications the environments can cause electrical performance to deteriorate due to the absorption of atmospheric moisture or electrostatic attraction of dust. Under extreme conditions, exposure to corrosive atmospheres or harsh chemicals, are just a couple of examples. In order to ensure reliability of these critical devices it is essential that the PCBs are protected to prevent reduced performance or in the worst case, complete failure. This protection can be offered in the form of a conformal coating or potting and encapsulation resins. Więcej informacji >

Effective Thermal Management

Dodatki: Thermal Management, Encapsulation Resins

During use, some electronic components can generate significant amounts of heat. Failure to effectively dissipate this heat away from the component and the device can lead to reliability concerns and reduced operational lifetimes. Newton’s law of cooling states that the rate of loss of heat is proportional to the temperature difference between the body and its surroundings. Therefore, as the temperature of the component increases and reaches its equilibrium temperature, the rate of heat loss per second will equate to the heat produced per second within the component. This temperature may be high enough to significantly shorten the life of the component or even cause the device to fail. It is in such cases that thermal management measures need to be taken. The same considerations can be applied to a complete circuit or device which incorporates heat producing individual components. Więcej informacji >
