Shielding electronic systems against electromagnetic interference (EMI) has become a hot topic. Technological advancements toward 5G standards, wireless charging of mobile electronics, in-package antenna integration, and system-inpackage (SiP) adoption are driving the need to apply more effective EMI shielding and isolation to component packages and larger modules. For conformal shielding, EMI shielding materials for exterior package surfaces have mostly been applied with a physical vapor deposition (PVD) process of sputtering, leveraging front-end packaging technologies to back-end packaging applications. However, sputtering technology challenges in scalability and cost along with advancements in dispensable materials are driving considerations for alternative dispensing techniques for EMI shielding.

Why embed the components? Embedded components have advantages over SMD because they are naturally screened from high frequency radio emissions (RFI or EMI). They can also be smaller than current SMD components. Both embedded and Mulpin components have these advantages, but Mulpin components have many more advantages and none of the disadvantages which can be seen below.

Copper pour is an essential design element in printed circuit boards (PCBs) that enhances thermal management, signal integrity, and electrical grounding. It involves filling unused areas on the board with copper, connecting them to power or ground planes. This feature helps manage heat dissipation, minimizes electromagnetic interference (EMI), and provides stable electrical grounding for complex circuits. While copper pour offers significant benefits, improper implementation may lead to manufacturing challenges like warping or soldering difficulties. This article explores the advantages of copper pour, the potential challenges, and how PCB Power integrates this design feature to optimize performance and durability. With advanced manufacturing processes, PCB Power ensures seamless copper pour integration for prototypes and large-scale production, offering turnkey PCB solutions for various industries.

Principle of shielding 1 The principle of shielding is creating a conductive layer completely surrounding the object you want to shield. This was invented by Michael Faraday and this system is known as a Faraday Cage. 2 Ideally, the shielding layer will be made up of conductive sheets or layers of metal that are connected by means of welding or soldering, without any interruptions. The shielding is perfect when there is no difference in conductivity between the used materials. When dealing with frequencies below 30 MHz, the metal thickness affects shielding effectiveness. We also offer a range of shielding methods for plastic enclosures. A complete absence of interruptions is not a realistic goal since the Faraday cage will have to be opened from time to time so electronics, equipment or people can be moved in or out. Openings are also needed for displays, ventilation, cooling, power supply, signals etc. 3 Shielding works in both directions, items inside the shielded room are shielded from outside influences.
