LTCC Multilayer Substrates(NL-Ag3)

The NIKKO LTCC substrates with Ag conductor material offer a multilayer substrate with low dielectric loss. Coils, capacitors, and resistors can be embedded in the internal layers. Ideal for high-frequency modules and silicon wafers interposer substrates.

Features

The NIKKO LTCC substrates can have embedded coils, capacitors, and resistors that allow reducing substrate size. Excellent dimensional tolerance of ±0.3% provides improves mounting accuracy. Low conductor loss is achieved by using Ag conductor material. Electroless Ni/Au plating or Electroless Ni/Pd/Au plating are available for surface treatment.
