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.

(Printed circuit boards are custom-made products, the picture and parameters shown are just
for reference)
General description
This is a type of 5 layer PCB built on mixed RF material RO4350B and textolite FR-4 for the
application of 2.4 Ghz Antenna. It's 1.0 mm thick with through holes. Green solder mask covers
both sides and immersion gold on pads. The base material is used from ITEQ and Rogers, entire
board supplying 1 PCB up. They're fabricated per IPC 6012 Class 2 using supplied Gerber data.
Each 25 boards are packed for shipment.
