1. It has the characteristics of small signal transmission loss, short transmission delay time and small signal transmission distortion.

　　2. Excellent dielectric properties (mainly: low relative dielectric constant Dk, low dielectric loss factor Df). Moreover, this dielectric property (Dk, Df) can maintain its stability under environmental changes in frequency, humidity, and temperature.

　　3. High precision control with characteristic impedance (Zo).

　　4. Excellent heat resistance (Tg), processability and adaptability.

　　Based on the above characteristics, high-frequency PCB boards are widely used in wireless antennas, base station receiving antennas, power amplifiers, components (shitters, confluence, filters), radar systems, navigation systems and other communication equipment.

　　Multi-layer high frequency plate design, based on cost savings, improving bending strength, electromagnetic interference control and other factors, often in the form of hybrid plate, called high frequency hybrid plate. The selection of high frequency mixed pressure materials and the design of overlapping combinations are varied, too numerous to list. And Chuangying circuit through research and development, experiment and trial production of a 6-layer board, the use of high-frequency material RO4350B/RO4450B and FR4 material combination mixed pressure.
