Embedded Capacitance Printed Circuit Boards

A 6-layer PCB on MC3TB embedded-capacitance core, 0.65±0.10mm thick. The MC3TB material adds a thin high-permittivity dielectric layer between the power and ground planes, so the planes themselves act as a distributed decoupling capacitor across the whole board area. This cuts the count of discrete bypass capacitors that would otherwise need to scatter around fast-switching ICs, frees up surface real estate for components or routing, and lowers the impedance of the power-delivery network into the high-MHz to GHz range where ordinary MLCCs already start to look inductive. Thin overall stackup keeps the design suitable for mid-density consumer and industrial assemblies. Typical fits are industrial microphone front-end boards, broadcast audio cards, instrumentation digitizer boards, mid-tier consumer audio gear, and noise-sensitive sensor electronics.
