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.

General description
This is a type of hybrid multilayer PCB (mixed material PCB) built on 10 mil RO4350B and FR-4
substrates for the application of Fleet GPS Tracking. It's standard 1.60 mm thick with 1oz copper
each layer, white silkscreen over green solder mask covering both sides. Immersion gold is plated
on pads and vias are tented. The base material is used from Rogers Corp. and ITEQ, entire board
supplying 1 up PCB. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25
panels are packed for shipment.
Features and benefits
The dielectric constant (DK) is low and stable, so the signal transmission is good without delay;
The temperature coefficient of dielectric constant is among the lowest of any circuit board material,
making it ideal for temperature sensitive applications;
SI performance improvement over the stack-ups with all FR4 board;
Cost reduction over stack-ups with all low loss material;
Long storage time, it can be stored for more than 1 year in vacuum bag;
High solderability, no stressing of circuit boards and less contamination of PCB surface;
RoHS materials;
Eligible products rate of first production: >95%
