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.

Embedded Passive Technology is a viable technology that has been reliably used in the defense and aerospace industry for over 20 years. Embedded Passive (Resistors and Capacitors) Technology have a great potential for high frequency and high density applications. It also provides better signal performance, reduced parasitic and cross talk. This paper summarizes the selection of resistor embedded materials, evaluations of resistive material (Phase 1) and duplication of a complex digital design (Phase 2). Phase 1 –resistive materials (Foil 25Ω/sq NiCr and 1kΩ/sq CrSiO) and resistive-Ply materials (25Ω/sq and 250Ω/sq NiP) were chosen for evaluation.

The high level of current interest in embedded passives in printed circuit boards is driven by the tremendous pressure to pack more circuitry into smaller spaces. However, adoption has been limited due to design, prototyping and infrastructure issues, as well as the stability and tolerances necessary for widespread replacement of discretes. The focus of this work has been to develop a polymer thick film resistor technology to incorporate reliable organic resistors inside printed wiring boards using standard PWB processing.

Embedding components within the PC board structure is not a new concept. Until recently, however, most embedded component PC board applications adapted only passive elements. The early component forming processes relied on resistive inks and films to enable embedding of resistor and capacitors elements. Although these forming methods remain viable, many companies are choosing to place very thin discrete passive components and semiconductor die elements within the PC board layering structure. In addition to improving the products performance, companies have found that by reducing the component population on the PC board's surface, board level assembly is less complex and the PC board can be made smaller, The smaller substrate, even when more complex, often results in lower cost. Although size and cost reductions are significant attributes, the closer coupling of key elements can also contribute to improving functional performance.This paper focuses on six basic embedded component structure designs described in IPC-7092.

The desire to have more functionality into increasingly smaller size end products has been pushing the PCB and IC Packaging industry towards High Density Interconnect (HDI) and 3D Packaging (stacked dies, embedded packaged components). Many companies in the high-end consumer electronics market place have been embedding passive chip components on inner PCB and IC Packages for a few years now. However, embedding packaged components on inner layers has remained elusive for the broader market due to lack of proper design tools and high cost of embedding components on inner layers (...) This paper will highlight several key industrialization aspects addressed in the frame of the European funded FP7 HERMES* project to build a manufacturing environment for products with embedded components. The program entered its third year and is now dealing with the manufacturing of functional demonstrators as an introduction to industrialization.

Embedded components technology has launched its implementation in volume products demanding high levels of miniaturization. Small modules with embedded dies and passive components on the top side are mounted in hand held devices. Smartphones have been the enablers for this new technology using the capabilities of embedded components. With this technological background another business field became interesting for embedded components – the embedded power electronics. The roadmap of the automotive industry shows a clear demand for miniaturized power electronic applications. Drivers are the regulations for the international fleet emissions which are focusing on three major trends.

Embedded computing systems used in many military and avionics applications are trending toward higher heat fluxes, and as a result performance is being hindered by thermal limitations. This is intensified by the high ambient conditions experience by today’s modern warfighter. In many applications liquid cooling is replacing air flow through chassis for both thermal and environmental benefits(...) This paper outlines a series of passive thermal improvements which are easily integrated into legacy, or existing, systems and can provide a 3-4x increase in dissipated power.
