6 FAQs about [What materials are used to embed capacitors ]
What materials can be used for embedded capacitors?
In this paper, we review three material options for embedded capacitors: thin FR4 epoxy-glass laminate, adhesiveless copper on polyimide substrate, and unsupported epoxy filled with high dielectric constant ceramic powder.
Can embedded capacitors be used in a standard lamination process?
There are other embedded capacitor materials that are inorganic, and thus they cannot be used in a standard lamination process used with other organic materials in PCBs and substrates. However, these can be used in two areas: Embedded dielectric foils like tantalum can be used on-die as a sintered layer.
Can small capacitors be embedded in a PCB or package substrate?
In addition to direct placement and assembly in a processor package, these components can be embedded in a PCB or package substrate. It is possible to embed small capacitors in an organic substrate, including the organic materials used to build PCB stackups and package substrates.
How are nanoscale materials used in embedded capacitor technology?
Various nanoscale materials have been used to address the challenges of embedded capacitor technology. In addition to the primary forms, such as nanoparticles, nanorods or nanowires, and nanotubes, there are other derivative macroscopic forms, such as nanoporous, nanotextured, or nanostructured .
Can a discrete capacitor be embedded in a PCB?
Discrete capacitors placed in PCBs and substrates are off-the-shelf components, designated low-profile MLCCs. While not specifically designed for embedding in substrates or PCBs, they can be embedded in these materials thanks to their lower-than-normal profile. These low-profile MLCCs from Murata can be used for embedding.
Why should capacitors be embedded in a board or substrate?
Thus, major motivating factors for embedding capacitors in a board or substrate are to improve performance through reduction of parasitics; to miniaturize systems further (reducing form factor, weight, and volume).
