Plastic housings used to enclose electronic equipment are electrically non-conductive. However, it is vital to ensure that the working components are effectively shielded from incoming interference signals, as well as preventing outgoing transmission to other equipment. A number of technologies have been developed to provide electrical conductivity within the structure of the housings. Electrically Conductive Fillers The obvious method of adding a conductive filler to the basic plastic resin from which the component is made has significant disadvantages:
Electrically Conductive Coatings It has become common practice to apply electrically conductive coatings, usually to the insides of mouldings. A number of different processes have been used commercially during the last three decades in which shielding technology has been developing, including:
Electrically Conductive Paint Over the last three decades electrically conductive paint has been found to be the most commercially successful coating process for the following reasons:
Metal Paint Coatings A number of electrically conductive metals have been used in this type of coating, including:
