Structure of 5G Package Substrates
The structure of a 5G Package Substrate is complex and includes multiple layers to accommodate the high-performance requirements of 5G applications. 主要な構造要素には次のものがあります。:
The core of the substrate is typically made of a high-performance material such as BT (ビスマレイミド トリアジン) resin, FR4, or ceramic. This core provides the mechanical strength and thermal stability necessary for reliable operation.
Multiple layers of conductive material, 通常は銅, are laminated onto the core. These layers form the electrical pathways that interconnect the various components. The design of these layers is optimized to handle high-frequency signals and minimize signal loss.
Dielectric layers made of materials like epoxy resin or advanced polymers are placed between the conductive layers. These layers provide electrical insulation and help maintain signal integrity by reducing crosstalk and electromagnetic interference (EMI).
Vias (vertical interconnect access) and microvias are used to create electrical connections between different layers of the substrate. These features are critical for maintaining the electrical continuity and integrity of the 5G device.
A surface finish such as ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) またはOSP (有機はんだ付け性保存剤) is applied to the external layers. This finish enhances solderability and protects the conductive traces from oxidation and corrosion.
A protective solder mask is applied to the surface of the substrate to prevent solder bridges and protect the underlying circuits from environmental damage.
