Product Details
Hello Guys,
The mixed high frequency PCB introduced today is 4-layer board on
Rogers core of 20mil RO4003C pressed with FR-4.
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 ounce.
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.
