Zum Beispiel, FR-4 (Flammhemmend-4) is a common glass fiber reinforced epoxy resin substrate with good insulation and mechanical strength, and is suitable for general electronic products. High-density interconnect boards (HDI) use more advanced materials with higher conductivity and smaller sizes, making them suitable for high-performance devices such as smartphones and computer chips.
Physical properties
The physical characteristics of a Packaging Substrate include its size, hierarchical structure, and connections between layers. Size is a key factor as it determines how many electronic components the substrate can accommodate. Hierarchical structure refers to the arrangement of different layers on the substrate, including single-layer, double-layer and multi-layer structures, which affects the complexity and density of the circuit. Inter-layer connection is the connection between layers, which must be reliable to ensure smooth communication of the circuit.
Electrical characteristics
The electrical characteristics of Packaging Substrate have an important impact on circuit performance. It includes properties such as resistance, Leitfähigkeit, and dielectric constant. Low resistance and high conductivity can reduce energy loss during signal transmission, thereby improving efficiency. The dielectric constant affects the signal propagation speed, which is especially important for high-frequency circuits. Choosing appropriate electrical characteristics is a key factor in ensuring stable circuit performance.
These key features jointly determine the scope of application and performance of Packaging Substrate.
