맞춤형 2레이어 리지드 FR-4 PCB: 동의하다 + Hard Gold Finish for High Reliability & 비용 효율성
Discover the industry “gold standard” for balanced performance and affordability. UGPCB’s 2-layer rigid FR-4 PCB, featuring TG150 high-temperature material and a dual ENIG + Hard Gold surface finish, delivers superior reliability for demanding applications.
나. Why Choose 2-Layer Rigid FR-4 PCB?
In the era of electronic miniaturization, 에 대한 수요 높은 신뢰성, 저렴한 비용, 그리고 compact design has made the 2-layer rigid PCB the “golden choice” for engineers and procurement managers. Unlike single-sided boards limited by routing space or expensive multi-layer boards, the 2-layer design strikes the perfect balance between performance and price.
UGPCB enhances this baseline by utilizing FR-4 TG150 heat-resistant material and a specialized 무전해 니켈 침지 금 (동의하다) + 하드 골드 표면 처리. This combination significantly improves durability and solderability, making it suitable for a wider range of harsh environments.

III. 제품 정의: What is a 2-Layer Rigid PCB?
1. 정의
에이 강성 PCB is a non-flexible printed circuit board composed of a substrate, copper foil traces, 솔더 마스크, and silkscreen. It establishes fixed electrical connections through drilling and etching processes.
에이 2-레이어 리지드 PCB (Double-Sided Board) is the foundational type of rigid PCB, featuring copper traces on both the top and bottom sides of the substrate. Electrical connections between layers are achieved via Plated Through Holes (vias).
2. Classification by Layer Count
- 1-층 (Single-Sided): Circuits on one side only. Lowest cost but severe routing limitations.
- 2-레이어 (Double-Sided): Circuits on both sides. Higher routing flexibility than single-sided; moderate cost. (UGPCB’s Specialty)
- Multi-Layer (4+ 레이어): Three or more copper layers. Suitable for complex circuits but significantly higher cost.
UGPCB’s 2-layer offering represents the highest cost-performance ratio in the rigid PCB category.
IV. Design Guidelines for High Reliability
With limited routing space on 2-layer boards, 준수 IPC-2221 design standards is crucial for signal integrity and thermal management.
1. Power and Ground Layout
- 접지면: Use large copper pours for Ground (접지) to minimize signal interference and EMI.
- Power Traces: Widen VCC traces to >20밀 to reduce resistance and voltage drop.
- Spacing: Maintain a minimum 10mil clearance between power and ground to improve filtering.
2. Signal Routing
- Differential Pairs: For high-frequency signals (USB, HDMI), use differential routing to reduce electromagnetic radiation.
- 3W 규칙: Maintain a spacing of ≥3x the trace width between signal lines to avoid crosstalk.
- Return Paths: Avoid signal traces crossing splits in the ground plane to prevent signal reflection.
3. 비아 디자인
- 구멍 크기: Minimize via diameter (예를 들어, 0.3mm) to save routing space.
- Via Tenting: Use solder mask to cover vias to prevent solder paste wicking during soldering.
- 고주파: Use through-hole vias (standard for 2-layer) to minimize parasitic capacitance compared to blind/buried vias.
다섯. Operating Principle: How PCBs Work
The core function of a PCB is to connect electronic components (작은 조각, 저항기, 커패시터) via copper traces to achieve predetermined electrical functions.
- 예: In a smartphone charging board, the PCB routes power from the USB interface to the charging management chip, distributes it to the battery, and feeds battery level data back to the system via signal lines.
- While the principle is identical to 다층 보드, 2-layer boards require meticulous layout planning to ensure 신호 무결성 (그리고) within limited space.
VI. 재료 & 성능: Why FR-4 TG150?
1. 기본 재료: FR-4 TG150
FR-4 (난연제 4) is the industry standard for epoxy resin glass cloth substrates.
- High Mechanical Strength: Reinforced by glass cloth, resisting bending and breakage.
- 열 안정성: TG150 (Glass Transition Temperature 150°C) ensures stability in high-temperature environments (industrial workshops, automotive engine compartments).
- 전기적 특성: 유전 상수 (DK) 4.2-4.5, 소산 인자 (Df) 0.02, making it suitable for high-frequency signal transmission.
- 화학 저항: Resists corrosion from solder and flux, extending service life.
2. 표면 마감: ENIG 2u” + Hard Gold 30u”
Surface finish acts as the PCB’s “protective shield.” UGPCB combines two finishes for maximum benefit:
- 동의하다 (무전해 니켈 침지 금): 에이 2u” (0.05μm) gold layer deposited chemically. Offers excellent planarity and solderability, ideal for fine-pitch components (예를 들어, 0.5mm pitch chips).
- 하드 골드 (Electrolytic Gold): A thick 30u” (0.76μm) gold layer plated electrically. Provides superior wear resistance and conductivity, perfect for frequent plug-in/unplug cycles (USB ports, SD card slots).
Comparison: This combination outperforms HASL (열기 솔더 레벨링) and standard OSP (유기 용해성 보존) in high-reliability applications like 산업 제어 그리고 자동차 전자.
VII. 구조 & 특징: Panelization Advantages
This PCB utilizes Matrix Panelization, where multiple individual PCBs (예를 들어, 10×10 array) are arranged on a larger production panel connected by Webs (Tabs).
Advantages of Panelization:
- Production Efficiency: Multiple PCBs produced simultaneously, reducing machine setup time.
- 비용 절감: Minimizes scrap material and maximizes material utilization.
- Assembly Ease: Webs can be separated via routing or V-Cut (V-Scoring) without damaging individual boards.
Additional Product Features:
- 높은 신뢰성: FR-4 TG150 + ENIG/Hard Gold withstands harsh environments (high temp, 습기, 진동).
- 저렴한 비용: Mature 2-layer process is 30%-50% 저렴합니다 than multi-layer boards.
- 맞춤화: Supports min. 0.1mm hole size, 분. 3Mil Trace/Space, and various finishes (침수은, OSP, 등.).
- Eco-Friendly: 준수 RoHS 규제 그리고 도달하다 표준; lead-free soldering ready for global export.

UGPCB’s workflow adheres strictly to IPC-A-600 (Quality Standard) 그리고 IPC-6012 (Performance Specification for Rigid PCBs).
- 절단: Shearing FR-4 laminate to required dimensions (예를 들어, 18″x24″).
- 교련: CNC drilling for component holes (0.3mm) 그리고 vias (0.2mm).
- Electroless Copper: Chemical deposition of 1-2μm copper for interlayer connectivity.
- Image Transfer: 포토레지스트 도포, exposing, and developing to transfer circuit patterns.
- 에칭: Removing excess copper to form final traces.
- 솔더 마스크: Coating with green solder mask ink, exposing, and curing to protect circuits.
- 표면 마감: 동의하다 (2u”) + 하드 골드 (30u”) plating for solderability.
- 실크 스크린: Printing component designators (R1, C2) and logos.
