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 mixed material multilayer PCB built on 20 mil RO4350B plus FR-4 substrate for
the application of satellite antenna. It's 1.69 mm thick, white silkscreen over green solder mask
on both sides and immersion gold is plated on pads and tracks. The base material is used from
Rogers and ITEQ, 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.
Features and benefits
RO4350B exhibits a stable dielectric constant over a broad frequency range;
Excellent high frequency performance due to low dielectric tolerance and loss;
SI performance improvement over the stack-ups with all FR4 board;
Cost reduction over stack-ups with all low loss material;
Long storage time which can be stored for more than 1 year in vacuum bag;
ISO9001, ISO14001, UL certified manufacturing factory;
PCB manufacturing on required specifications;
No MOQ, low cost for prototypes and small runs quantity;
8000 types of PCB per month;
Application
LNA, Radar data acquisition converter,Spread spectrum, 3G antenna
