AI Technical Summary
Existing thermosetting resin compositions used in antenna devices and printed circuit boards face challenges with mesh clogging during filtration, making it difficult to implement on an industrial scale, and there is a need for materials with high relative permittivity (Dk) and low dielectric loss tangent (Df) to handle high-frequency signals effectively.
A thermosetting resin composition containing amorphous titanate, such as calcium titanate, obtained by firing at 1,150°C or higher, which exhibits excellent mesh release properties and enhances the relative permittivity of the substrate material, allowing for the production of laminates suitable for high-frequency signals.
The composition achieves improved mesh filtration properties and increased relative permittivity, facilitating the miniaturization of antenna modules and communication equipment while maintaining low dielectric loss, thus enhancing communication quality and speed.
