High-Performance BGA IC Substrate: The Precision Foundation for Advanced IC Packaging

In the era of smaller, faster, and more powerful electronics, advanced IC packaging is critical. Acting as the essential interface between the silicon die and the main แผงวงจรพิมพ์ (พีซีบี), ที่ พื้นผิว BGA IC is the core component of high-end semiconductor packages. UGPCB leverages deep การผลิต PCB expertise and advanced processes to deliver high-performance, เชื่อถือได้ BGA package substrate การแก้ปัญหา.

1. What is a BGA IC Substrate?

A BGA IC Substrate is a specialized type of การเชื่อมต่อระหว่างกันที่มีความหนาแน่นสูง (HDI) พีซีบี designed explicitly for Ball Grid Array (BGA) การบรรจุหีบห่อ. It is not a standard แผงวงจร but a precision multilayer interconnect structure. One side interfaces with the die via ultra-fine circuitry, while the opposite side connects to the main บอร์ด PCB through an array of solder balls, fulfilling four key functions: electrical interconnection, signal transmission, การกระจายความร้อน, and physical support.

 

2. Design Essentials & Operational Principle

Design Essentials:

1. Ultra-High Wiring Density: To accommodate increasing I/O counts, substrates require ultra-fine line design. UGPCB reliably achieves 30μm/30μm minimum line width/space, enabling efficient fan-out routing for high-pin-count chips.

2. Precise Registration & Dimensional Stability: Alignment between die and solder balls must be extremely accurate. Our core material, มิตซู แก๊ส HF BT HL832NX-A-HS, offers a low CTE (ค่าสัมประสิทธิ์การขยายตัวทางความร้อน) และความเสถียรของมิติที่ดีเยี่ยม, preventing warpage and misalignment caused by thermal stress.

3. Reliable Microvias: Layer-to-layer interconnection depends on laser-drilled blind vias. ของเรา 0.075mm laser drilling capability facilitates high-density vertical connections (เช่น, 1-2, 3-4 ชั้น), ensuring signal integrity.

4. Optimized Signal & ความสมบูรณ์ของพลังงาน: A carefully designed stack-up (เช่น, 1L-4L, 1L-2L, 3L-4L as per your specs) and plane allocation provide low-loss paths for high-speed signals and clean, stable power delivery to the chip.

Operational Principle:

The die is attached to the substrate’s top surface (typically Layer 1) via wire bonding or flip-chip technology. Electrical signals from the chip are routed, redistributed (อาร์ดีแอล), and transmitted through the substrate’s internal ultra-fine traces และ microvias (laser/mechanical holes). They finally exit via the solder ball array on the bottom surface to connect to the larger พีซีบี (การประกอบ PCB). It is essentially a miniaturized, chip-specific, high-end แผงวงจรพิมพ์.

3. Core Material, โครงสร้าง & คุณสมบัติที่สำคัญ

• Core Material: มิตซู แก๊ส HF BT HL832NX-A-HS high-performance laminate. Renowned for its ค่าคงที่ไดอิเล็กตริกต่ำ (ดีเค), low dissipation factor (ฟ), high thermal resistance (high Tg), and exceptional dimensional stability, it is the ideal choice for high-speed, high-frequency IC packaging substrates.

• Key Structure: 4-layer build with stacked via design (1-2, 3-4 layer blind vias) for greater routing density. The overall PCB thickness is 0.3mm, meeting thin-profile packaging requirements.

• พื้นผิวเสร็จสิ้น:****เกี่ยวกับ enepic (อิเล็กโทรไลต์นิกเกิลอิเล็กโทรไลเซิลแพลเลเดียม, 2ม.”). This finish combines nickel’s barrier properties, palladium’s corrosion resistance, and gold’s superior solderability. It is the preferred choice for fine-pitch BGA solder ball attachment, ensuring long-term reliability.

• หน้ากากบัดกรี & Opening: We use ไทโย PSR4000 AUS308 high-performance Liquid Photoimageable Solder Mask (LPSM), known for high resolution and reliability, perfectly defining openings for 0.1mm mechanical through-holes and pads.

4. การจำแนกประเภท & แอปพลิเคชันหลัก

• การจำแนกประเภท: Primarily categorized by interconnection method: Wire Bonding Substrates และ Flip Chip Substrates. The specifications provided (ultra-fine lines, เกี่ยวกับ enepic) are particularly suited for Flip Chip and other advanced packaging applications.

• แอปพลิเคชันหลัก:

  • Central Processing Units (CPU/GPU) การบรรจุหีบห่อ

  • Mobile Device Application Processors (AP) & Baseband Chips

  • High-Speed Networking & Communication Chips (เช่น, เอฟพีจีเอ, เอสิค)

  • ปัญญาประดิษฐ์ (AI) & Machine Learning Accelerators

  • Advanced Memory Packaging (เช่น, HBM)

  • These applications represent the core of ความหนาแน่นสูง, high-performance PCBA ออกแบบ.
