Conductive copper or other substance-based coating is used for electromagnetic shielding of electronic equipment, the emissions of which could cause interference with other devices.<\/em><\/h3>\n

There are some enclosures, panels or elements that can only be made of plastic, and not of metal, because the object outside must not be electrically conductive, but at the same time it must be shielded so as not to interfere electronically with others components<\/strong>.\nA particular need felt, and often imposed by specific regulations, in certain sectors such as telecommunications, medical, military, automotive, etc.<\/p>\n

Conductive copper coating and types of shielding<\/h2>\n

To respond to this request, we perform an electromagnetic shielding process<\/strong> to complete a range of processes ranging from light metal to plastic carpentry, from aesthetic coating to screen printing, from laser cutting and engraving to 3D printing.\nA copper-conductive coating<\/strong> is usually used, formulated to ensure good adhesion to almost all plastic materials.<\/p>\n

The finish, with a thickness of a few microns, is resistant to abrasion, humidity and heat. On request, however, conductive coating based on nickel, silver, graphite, etc. can be used depending on the level of electromagnetic emissions of the components which will be housed in the enclosure.\nThe conductive copper coating offers effective protection against electrostatic discharge (ESD<\/strong> \u2013 ElectroStatic Discharge<\/em>) and good EMI<\/strong> shielding ( ElectroMagnetic Interference<\/em>), i.e. against electromagnetic interference radiated from the outside or inside<\/strong>: the electrical or electronic components in the shielded enclosure will continue to function properly when subjected to external electromagnetic interference and in turn they will not be a source of interference that could disturb other electronic devices.<\/p>\n

Shielding coating processes<\/h2>\n\n

The process takes place inside a coating<\/strong> booth<\/strong> with operating modes similar to the liquid painting process.\nThe parts not to be coated are masked<\/strong> with the manual application of a specific masking tape. In this way, the conductive coating can be applied with greater accuracy only inside the plastic enclosure, without damaging the external part.<\/p>

Where possible, for reasons related to the shape of the object to be coated or the quantities involved, we produce specific masking templates in order to streamline the process. In any case, the coating is done manually.<\/strong><\/p>\n

Why rely on MCS?<\/h2>\n

\u00abWhen we talk about shielding coating, we are referring to all in all niche sectors, with a limited production of pieces\u00bb underlines Alessandro Vignaga, Sales Manager of MCS.\n\u00abSome companies could therefore carry out the coating themselves as spray painting systems are available on the market.<\/p>\n
