Let's take a look at the 10- layer HDI board. HDI ( High Density Interconnector ) is a circuit board made using microvia technology. A 10- layer HDI board means that there are 10 layers of circuits in the circuit board, and each layer is connected by microvias. The main features of this circuit board are small size, light weight, and fast signal transmission speed.
The detailed parameters of the 10- layer HDI board mainly include:
1. Material: Usually FR-4 or high-frequency materials are used, which have good electrical performance and stability.
2. Number of layers: 10 layers, each layer is connected by micro holes.
3. Pore diameter: The diameter of micropores is generally less than 50um .
4. Line width / line spacing: Line width / line spacing is generally less than 20um .
5. Impedance: Depending on the design requirements, the impedance can be between tens of ohms and hundreds of ohms.
6. Surface treatment: Surface treatment methods such as gold plating, silver plating, and tin spraying can be used to improve weldability and corrosion resistance.
