PCB de substrato de componente UGPCB | 0.3mm Fino | 75μm Fine Line – HDI Solution

In the realms of semiconductor packaging and high-end electronics manufacturing, as chip functionalities grow increasingly complex and product sizes shrink, o substrate that carries and interconnects delicate chips has become central to determining product performance and reliability. O PCB do substrato do componente de UGPCB is engineered precisely for this challenge. Utilizing advanced Substrate-Like PCB (SLP) processes and top-tier materials, it is specifically designed for advanced packaging and miniaturized components that demand ultra-high wiring density, exceptional signal integrity, and utmost reliability.

Visão geral do produto: Definição & Core Value Proposition

A Component Substrate PCB is a specialized type of placa de circuito impresso that acts primarily as the critical interconnection bridge between a semiconductor chip and the main motherboard. Unlike standard PCBs, its design rules are closer to those of Substratos IC used in semiconductor packaging but find broader application in carrying various active and passive componentes eletrônicos to form a complete functional sub-module.

Think of it as the “micro-skeleton” and “neural network” of an electronic device. After a wafer is diced into individual chips, they are first precisely packaged onto such a substrate before being assembled onto a larger main PCB. Portanto, the substrate’s performance directly dictates the ultimate effectiveness of the chip it carries. UGPCB’s product targets the urgent need for miniaturization and high functional integration in premium consumer electronics, AI hardware, and advanced communication equipment.

Detailed Technical Specifications

This component substrate from UGPCB represents a high level of precision manufacturing, with its core specifications as follows:

• Contagem de camadas & Estrutura: 2-layer design, providing precise double-sided interconnection within an ultra-thin profile for a compact structure.

• Espessura da placa: 0.3milímetros overall thickness, saving crucial internal space for ultra-slim device designs.

• Line Fineness: Suportes minimum line width/space of 75 micrometers (μm), enabling high-density routing in a minimal area, which is fundamental for complex functionalities.

• Conductive Via Capability: Características minimum drill hole size of 0.25mm, ensuring reliable, high-density electrical connections between layers.

• Acabamento superficial: Utilizes Hard Gold revestimento. The gold layer offers excellent wear resistance, oxidation resistance, and can withstand repeated insertions and harsh environments, guaranteeing long-term contact reliability—ideal for connectors and critical test points.

• Máscara de solda & Materiais: Employs high-performance PSR-4000 WT03 solder mask ink for superior insulation and heat resistance. The core material is CC-HL820WDI, known for its exceptional dimensional stability and low Coefficient of Thermal Expansion (CTE). This effectively reduces stress caused by temperature fluctuations during soldering and operation, preventing circuit breakage or connection failure with the chip.

Considerações de design & Princípio Operacional

Critical Design Focus

Designing a Component Substrate PCB requires thinking beyond conventional PCB rules, focusing on:

1. Signal Integrity First: The ultra-fine 75μm lines necessitate strict impedance control. Design must thoroughly account for the impact of skin effect and crosstalk on high-speed signals.

2. Co-Design for Thermal Management: As the primary seat for the chip, the substrate is a key heat dissipation path. It requires using high-thermal-conductivity materials and intelligent design of thermal vias and copper planes to efficiently draw heat away from the chip.

3. Mechanical Stress Compatibility: A core challenge is matching the differing CTE between the silicon chip and the substrate. The low CTE characteristic of CC-HL820WDI material is key to minimizing solder joint fatigue failure due to thermal cycling, thereby enhancing product lifespan in demanding environments.

How It Works: A Brief Explanation

The fundamental operating principle of a component substrate is to provide the semiconductor chip with a three-dimensional platform for electrical interconnection, suporte físico, and thermal management.

• Electrical Connection: Through its internal precision copper traces and micro-vias, it “translates” and “reroutes” the hundreds or even thousands of micron-scale pads on a chip into larger, more manageable footprints for easy soldering and routing on the main PCB.

• Suporte físico: Provides a robust mechanical platform for the fragile silicon die, protecting it from physical damage.

• Environmental Protection: Protects the internal fine-line circuitry from moisture, dust, and chemical corrosion through the solder mask and potential underfill.
