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 Mixed PCB On RO4350B 0.254 mm +
FR4 0.3 mm With OSP
(Printed circuit boards are custom-made products, the picture and parameters shown are just
for reference)
General description
This is a type of 4 Layer PCB mixed 0.254mm (10 mil) RO4350B and 0.3mm FR-4 for the
application of Wireless Surveillance System. It's multiblock construction, so there're few
different boards inside. Keep out lines are outer contour of the milling cutter. When you
have several different prototype PCB jobs for trial market, this is a good economical way
to help you save the production cost that is merging these different PCBs together to be
manufactured simultaneously on one panel. Does it sound cool?
Basic specifications

Features and benefits
RO4350B exhibits a stable dielectric constant over a broad frequency range. This makes it
an ideal substrate for broadband applications;
SI performance improvement over the stack-ups with all FR4 board;
Cost reduction over stack-ups with all low loss material;
Good oxidation resistance and good heat dissipation;
ISO9001, ISO14001, UL certified manufacturing factory;
AOI inspection;
Powerful PCB capabilities support your research and development, sales and marketing;
16000 square meter workshop;
30000 square meter month capability;
Application
GPS antenna, Communications relays, Analogue transmitter, 4G antenna
