IC Substrate PCB

As a critical bridge between silicon dies and standard PCBs, our IC Substrate (Package Substrate) manufacturing service provides the essential high-density interconnect platform for modern chip packaging. We specialize in producing ultra-fine line PCBs that meet the demanding electrical, thermal, and physical requirements of BGA, CSP, FC-CSP, SiP, and other advanced packages, enabling higher performance, miniaturization, and reliability for your semiconductor devices.

Core Capabilities & Technologies

High-Density Interconnect (HDI): Expertise in 2+N+2, 3+N+3, and any-layer HDI builds with laser microvias (as small as 50µm) to accommodate high I/O count and fine-pitch chips.
Ultra-Fine Line Tracing: Capable of trace/space down to 15µm/15µm, supporting the most demanding routing densities for leading-edge packaging.
Advanced Materials: Utilization of specialized substrates with tailored CTE (Coefficient of Thermal Expansion), such as BT (Bismaleimide Triazine), ABF (Ajinomoto Build-up Film), and low-loss high-frequency materials for optimal electrical and thermal performance.
Precise Surface Finishes: Offerings include ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold), ENIG, and selective hard gold for reliable wire bonding and flip-chip interconnection.
Strict Process Control: Comprehensive control over impedance, dielectric thickness, and copper profile to ensure signal integrity and power delivery for high-speed semiconductor applications.

Key Features & Benefits

Minaturization Enabler: Supports the trend towards smaller, thinner, and more powerful electronic devices through superior packaging density.
Enhanced Electrical Performance: Optimized design and material selection minimize signal loss, power noise, and latency for high-speed chips (processors, FPGAs, ASICs).
Superior Thermal Management: Provides effective heat dissipation pathways from the chip to the motherboard, critical for device reliability and performance.
High Reliability: Rigorous testing for interconnect integrity, ensuring robustness under thermal cycling and mechanical stress typical in packaged environments.
