Brief Introduction
With the development of electronic communication technology, the communication frequency
is becoming higher and higher, and the high frequency signal transmission, need to use low
dielectric constant (Dk), low dielectric loss (Df) but expensive special materials. These materials
have cyanate and high frequency materials such as polytetrafluoroethylene / ceramic based materials
(PTFE/Ceramic), hydrocarbons / ceramic based materials (Hydra Carbon/Ceramic). Usually these
materials are expensive.
Reducing the cost is an important means for customers to improve the competitiveness of products.
Therefore, the customers adopt the laminated structure of mixed materials in the design of PCB
structure, that is, the necessary signal layer uses high-frequency materials to meet the needs of
signal transmission. Other line layers are made of conventional fiberglass epoxy FR-4, which we
call a hybrid board.
