AI Technical Summary

Technical Problem

Existing Low Temperature Co-fired Ceramics (LTCC) materials face challenges in ultra-high frequency bands of 6G communication due to increased signal loss, electromagnetic interference, reduced reliability, and heat dissipation limits, necessitating the development of materials that simultaneously achieve high strength, low dielectric constant, and low loss characteristics.

Method used

An LTCC composition comprising silica and alumina frit, silica and alumina fillers, and hexagonal boron nitride fillers with specific ratios and properties is used, along with a manufacturing method involving low-temperature co-firing to produce a ceramic electric device with improved dielectric constant, strength, and thermal conductivity.

Benefits of technology

The solution achieves a dielectric constant of 3.75 to 4.05, strength of 235 to 265 MPa, and thermal conductivity of 1.3 to 2.1 W/mK, enabling stable signal transmission and long-term reliability in ultra-high frequency bands, suitable for 6G communication environments.
