What are IC Substrate PCBs?
Key Characteristics of IC Substrates
Small Form Factor & Thin Profiles
IC substrates are small and thin. This point is noticeable when you compare them to regular PCBs. They fit in compact devices.
High-Density Interconnections
IC substrates have fine lines and traces with small spaces. This allows many connections in a small area.
Microvias & Advanced Via Technology
IC substrates use microvias, tiny holes made by lasers, to connect layers. Blind and buried vias are used for complex connections.
Material Variety
Many materials are used for IC substrates, for instance, FR4, BT Resin, ABF Resin, Polyimide, and Ceramic. Each material has different properties, depending on the substrate’s use.
Types of IC Substrates We Manufacture
BT Substrate (Bismaleimide Triazine Substrate)
- Made of BT resin.
- Used for mid-to-low-end IC packaging like memory chips and consumer electronics.
- Offers good heat resistance and electrical properties at a lower cost.
ABF Substrate (Ajinomoto Build-up Film Substrate)
- Uses ABF as insulation.
- Best to use in high-end IC packaging such as CPUs, GPUs, and high-speed communication chips.
- Suited for multi-layer, high-density interconnections (HDI). You can incorporate it for advanced packaging.
Ceramic Substrate
- Made of Al₂O₃, AlN, or Si₃N₄.
- Features excellent thermal conductivity and high reliability for high-power IC packaging.
- Used in power devices, RF components, and high-speed communication.
Metal Core Substrate
- Uses aluminum, copper, or stainless steel as the core.
- Offers high thermal dissipation for LED packaging and power devices.
- More cost-effective than ceramic while meeting heat management needs.
Fan-Out Substrate
- Uses Fan-Out Packaging technology.
- Reduces substrate use with Wafer-Level Packaging (WLP), increasing interconnection density.
- Used in high-end smartphone chips, AI chips, and high-performance computing.
High-Frequency Substrate:
- Made from PTFE, LCP, or PI.
- The material serves applications in 5G technology together with millimeter-wave radar systems and high-speed data communication functions.
- It carries low dielectric constant (Dk) and low dielectric loss (Df) for signal transmission.
BGA Substrates | Ball Grid Array: BGA substrates are incorporated for ICs with many pins. Is performance is also impeccable.
