Embedded Component PCB with Buried Resistors and Capacitors for Miniaturized Electronics

Embedded Component PCB (also known as buried component PCB) integrates passive components – resistors, capacitors, and even bare silicon dies – directly into the internal layers of the board, rather than mounting them on the surface.

This advanced technology improves electrical performance, releases surface space, eliminates solder joints, and enhances reliability.

Embedded resistors are typically fabricated using thin-film nichrome (NiCr) or nickel-phosphorus (NiP) alloys deposited on copper foil, while embedded capacitors utilize thin dielectric layers to form capacitance within the board structure.

The AC impedance between power supply and ground can be reduced to 10 milliohms using buried capacitor technology alone.

Available in configurations including embedded resistor, embedded capacitor, and combined embedded passive designs, these boards deliver superior signal integrity, reduced parasitic effects, and significant space savings for high-density applications.
