You must be presuming that PVD coating is used for EMI RFI Shielding. PVD is the abbreviated form of physical vapour deposition. Its coatings or thin film coating can bring quantifiable advantage to a diversity of parent materials used for EMI RFI shielding. Digging deep into the meaning of EMI RFI shielding. It is quite simply put, it is the means to remove or lessen electromagnetic interference or common radio interference. Following the enormous growth of electronics products, both consumer and industrial, safety and security using these devices will be assured by the company.
Be it any field- military, aerospace, medical or consumer related, our lives hinge on on electronics. Their effective failure, disturbance or damage, can have disastrous outcomes. Devices get smaller and smaller, minimizing the permissible paths of energy propagation. Workstations are getting faster and faster. The result is more and more interference. And that is why the need for electromagnetic protection is a growing concern.
The task is to come up with an effective solution. The solution to this is that we must reflect, transmit, filter or ground. That is attained by adding a conductive surface to the specific environment, so the wave of energy can be transmitted to another source. According to a fact called “Faraday Cage”, introduced by Michael Faraday says we can eradicate disruption or damage by offering a conductive enclosure. An innovating way of doing that is through thin film coatings. They are strongly rigid and squashy, can be useful to a variety of materials, in a variety of conductive coating material choices, like aluminum, copper, nickel and chrome. In addition, these coating processes are environmentally friendly and yield no bi-products. That is particularly significant with the emerging RoHS, ELV and WEEE Directives that affect protective coating, too.
Furthermore, in your next product design necessitating EMI RFI shielding, go with PVD coating.
