In response to the growing need for miniaturization and low profile of modules in the electronic component market and the growing need for low dielectric loss in the telecommunications market, Yamamura Photonics has been developing green sheets for high-strength LTCC substrates and green sheets for low-dielectric loss LTCC substrates.

Green sheets for high-strength LTCC substrates are materials that can support higher performance, smaller size, and lower profile of electronic components and modules while increasing the bending strength of the substrate to the same level as that of alumina substrates. Since the substrates can be sintered at low temperature while having excellent strength, it is possible to use low resistance conductors (Ag, Au, etc.) that cannot be used for HTCC (high temperature co-fired ceramics) substrates.

Green sheets for low dielectric loss LTCC substrates are materials that realize an ultra-low dielectric loss in the sub-6 band (3.6 to 6 GHz) and millimeter-wave band (over 28 GHz) used for 5G communication. Conventionally, LTCC substrates have been used for components in communication devices such as circuit boards and filters that process signals. In addition, we are developing more optimal materials for high-frequency band applications that require even lower dielectric loss.
