Rogers 4 Layer Hybrid PCB On 20mil RO4003C and FR-4 |

Stack-up |

|
|
Firstly, it's a 4 layer structure. Layer 1 to layer 2 is 20mil Rogers core, which are the main wiring layers for the signal lines. Layer 3 to layer 4 is the FR-4 core, which is connected |
|
|
by the Prepreg of FR-4. Each layer is connected by plated through holes. This is a better method to keep the board cost effective. The inner layer and out layer of copper is 1 oz. |

Let's take a look at its microsection 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. |
