What is a Gold-Plated (이머젼 골드) Double-Sided PCB?

Definition and Basic Concept

에이 양면 PCB is a circuit board that features conductive copper layers on both its top and bottom surfaces, allowing for more complex and dense circuit routing compared to single-sided boards. 용어 “gold-plated” in our context specifically refers to the 이머젼 골드 (동의하다) 표면 마감. This is a critical final step in the PCB 제작 process where a thin layer of gold is chemically deposited over a nickel barrier layer on the copper traces. 이 조합은 플랫을 제공합니다., oxidation-resistant, and highly solderable surface, making it ideal for double-sided PCB fabrication and subsequent PCBA 조립.

In-Depth Specifications and Material Composition

The Building Blocks of Quality

The superior performance of our double-sided boards is rooted in the careful selection of materials and precise control of parameters:

• 핵심 자료: High-quality FR4, a flame-retardant glass-reinforced epoxy laminate. This material offers an excellent balance of mechanical strength, 전기 절연, 그리고 비용 효율성.

• Board Structure: 2 레이어 of copper foil, firmly bonded to the FR4 substrate.

• 표면 처리: 이머젼 골드 (동의하다). This process creates a flat surface crucial for modern components, protects the underlying copper, and provides a long shelf life.

• 구리 두께: 1온스 (approximately 35µm), a standard and robust weight that handles typical current loads in digital circuits effectively.

• 완성된 두께: 1.2mm, offering a rigid and durable board structure for most applications.

• Critical Design Rules: Minimum Trace/Space of 6mil (0.15mm), enabling a good level of design density for complex digital circuits.

• 솔더 마스크: Available in Green or White, providing insulation and protection against oxidation and solder bridges.

Key Advantages and Product Features: Why Choose UGPCB’s Immersion Gold PCB?

Unmatched Reliability and Performance

Choosing our gold-plated double-sided PCB translates to tangible benefits for your project:

1. Superior Flatness and Solderability: The ENIG finish is exceptionally flat, which is vital for reliably soldering fine-pitch components like BGAs and QFNs. This directly reduces defects in your PCB 프로세스.

2. Excellent Oxidation Resistance: The gold layer is inert, preventing the copper from tarnishing over time. This ensures a reliable surface for soldering even after prolonged storage, making your PCB 프로토타입 and production inventory more manageable.

3. Stable Contact Surface for Connectors: The hard, durable gold surface is ideal for edge connectors and test points, providing a low-resistance, wear-resistant contact interface.

4. Dual-Sided Routing Capability: Effectively doubles the available area for routing traces compared to a single-sided board, allowing for more compact and efficient digital circuit board 디자인.

5. 비용 효율성: For designs that don’t require the complexity of a 4-layer board, the double-sided FR4 PCB with ENIG finish offers the best performance-to-cost ratio for a wide range of applications.

• Prototyping and R&디: The ideal choice for functional PCB prototypes that closely mimic final production performance.

The Manufacturing Workflow: A Glimpse into Precision Engineering

디자인에서 배달까지

The production of a high-quality double-sided PCB is a meticulous process:

1. 재료 준비 & 교련: The FR4 panel is prepared, and via holes are precision-drilled to create interconnections between layers.

2. Plating Through Hole (PTH): A conductive layer is chemically deposited inside the drilled holes to establish electrical connectivity between the two sides.

3. Pattern Imaging & 개발: The circuit pattern is transferred onto the copper layers using photoresist and UV light.

4. 에칭: Unwanted copper is chemically etched away, leaving behind the desired circuit traces.

5. 솔더 마스크 적용: The green or white solder mask is applied and cured, exposing only the component pads and vias.

6. 표면 마무리 – 이머젼 골드: The board undergoes the ENIG process, applying the nickel barrier and thin gold layer.

7. 실크스크린 인쇄: Component designators and logos are printed on the board.

8. 전기 테스트 & 최종검사: Each board is rigorously tested for continuity and short circuits to ensure 100% functionality before shipment.

Design Considerations and Best Practices

Optimizing Your Board for Success

To fully leverage the capabilities of this 양면 PCB, consider these design tips:

• Utilize Vias Effectively: Strategically place vias to create short and efficient signal return paths between layers.

• Power Plane Strategy: While a full ground plane is ideal, you can use generous copper pours on both sides to create a stable power distribution network for your digital PCB.

• Respect the 6mil Rule: Adhere to the minimum trace and space requirements to ensure manufacturability and yield.

• 구성 요소 배치: Place critical and noise-sensitive 구성 요소 on one side (typically top) to simplify routing and minimize interference.
