Hello everyone,

Warm greetings!

Today we talk about 4-layer hybrid PCB built on 20mil RO4003C and FR-4.

Firstly, it's a 4 layer structure. Layer 1 to layer 2 is 20mil RO4003C core, which is the main wiring layer for the signal lines. Layer 3 to layer 4 is the core of FR-4, both cores are combined through 0.2mm prepeg. Each layer is connected by plated through holes. The inner layer and out layer of copper is 1 ounce. This is a good method to keep the board cost effective.

Let's take a look at its micro-section chart.

Here on the left is the PTH hole, the bottom is layer 1 to layer 2 which is high frequency material, the upper part is glass fiber material. The finished thickness of the plate is 1.6mm.

The color of solder mask and silkscreen are also commonly used in green and white. Surface finish on pads is immersion gold.

Following is another type of 20mil RO4003C hybrid PCB. It’s made of 2 cores of 20mil RO4003C.

The applications of 20mil RO4003C hybrid PCB is wide, such as LNA, optical coupler, balanced amplifier, duplexer etc.

The advantages of 20mil RO4003C hybrid PCB are reflected in following 3 points:

1) RO4003C exhibits a stable dielectric constant over a broad frequency range. This makes it an ideal substrate for broadband applications.

2) Reducing signal loss in high frequency application meets the development needs of communication technology.

3) Cost reduced over stack-ups with all low loss material;

Our PCB Capability (Hybrid Design)

At present, the mature mixed pressing materials are as follows:

RO4350B + FR4;

RO4003C + FR4;

F4B + FR4;

RT/duroid5880 + FR4

RT/duroid5880 + RO4350B
