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.

PCB Case: 4 Layer Hybrid PCB With RO4003C + FR4
Combined
(PCB's are custom-made products, the picture and parameters shown are just for reference)
General description
This is a type of high frequency PCB built on RO4003C and FR4 combined for the application of
analogue transmitter. It's a 4 layer RF PCB board at 1.1 mm thick. It's immersion silver finish with
blue solder mask and white silkscreen. It's fabricated per IPC 6012 Class 2 using supplied Gerber
data. Each 20 boards are packed for shipment.
Features and benefits
The characteristic of low dielectric loss makes the signal loss at a lower level, which makes the
signal transmission of the whole equipment excellent.
Stable electrical coefficient of dielectric constant.
Delamination of copper foil will not be caused by the change of cold and heat due to the consistency
with the thermal expansion coefficient of copper foil.
Immersion gold has excellent surface planarity, particularly helpful for PCBs with BGA packages
or even CSP mounted components to reduce failure rate during assembly and soldering.
PCB manufacturing is strictly as per required specifications.
Meeting your printed circuit board needs from PCB prototyping to mass volume production.
Reduce manufacturing cost from advanced equipment import, worker training and technology
improvement and management.
