High-Performance BGA IC Substrate: The Precision Foundation for Advanced IC Packaging
In the era of smaller, أسرع, and more powerful electronics, advanced IC packaging is critical. Acting as the essential interface between the silicon die and the main لوحة الدوائر المطبوعة (ثنائي الفينيل متعدد الكلور), ال BGA IC Substrate is the core component of high-end semiconductor packages. UGPCB leverages deep تصنيع ثنائي الفينيل متعدد الكلور expertise and advanced processes to deliver high-performance, موثوق BGA package substrate الحلول.
1. What is a BGA IC Substrate?
A BGA IC Substrate is a specialized type of ربط عالية الكثافة (مؤشر التنمية البشرية) ثنائي الفينيل متعدد الكلور designed explicitly for Ball Grid Array (بغا) packaging. It is not a standard لوحة الدائرة but a precision multilayer interconnect structure. One side interfaces with the die via ultra-fine circuitry, while the opposite side connects to the main لوحة ثنائي الفينيل متعدد الكلور through an array of solder balls, fulfilling four key functions: electrical interconnection, نقل الإشارة, تبديد الحرارة, and physical support.

2. Design Essentials & Operational Principle
Design Essentials:
-
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.
-
Precise Registration & Dimensional Stability: Alignment between die and solder balls must be extremely accurate. Our core material, Mitsubishi Gas HF BT HL832NX-A-HS, offers a low CTE (Coefficient of Thermal Expansion) and excellent dimensional stability, preventing warpage and misalignment caused by thermal stress.
-
Reliable Microvias: Layer-to-layer interconnection depends on laser-drilled blind vias. ملكنا 0.075mm laser drilling capability facilitates high-density vertical connections (على سبيل المثال, 1-2, 3-4 طبقات), ensuring signal integrity.
-
Optimized Signal & Power Integrity: A carefully designed stack-up (على سبيل المثال, 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 (RDL), and transmitted through the substrate’s internal ultra-fine traces و microvias (laser/mechanical holes). They finally exit via the solder ball array on the bottom surface to connect to the larger ثنائي الفينيل متعدد الكلور (تجميع ثنائي الفينيل متعدد الكلور). It is essentially a miniaturized, chip-specific, high-end لوحة الدوائر المطبوعة.
3. Core Material, Structure & الميزات الرئيسية
-
Core Material: Mitsubishi Gas HF BT HL832NX-A-HS high-performance laminate. Renowned for its low dielectric constant (DK), low dissipation factor (ص), 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.
-
الانتهاء من السطح:****ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold, 2μ”). 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.
-
قناع اللحام & Opening: We use TAIYO 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.
