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

Definition and Basic Concept

อัน PCB สองด้าน 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. คำว่า “gold-plated” in our context specifically refers to the ทองแช่ (เห็นด้วย) พื้นผิวเสร็จสิ้น. This is a critical final step in the การผลิต PCB process where a thin layer of gold is chemically deposited over a nickel barrier layer on the copper traces. This combination provides a flat, oxidation-resistant, and highly solderable surface, making it ideal for double-sided PCB fabrication and subsequent แอสเซมบลี PCBA.

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:

Core Material: High-quality FR4, a flame-retardant glass-reinforced epoxy laminate. This material offers an excellent balance of mechanical strength, electrical insulation, and cost-effectiveness.
Board Structure: 2 เลเยอร์ of copper foil, firmly bonded to the FR4 substrate.
การรักษาพื้นผิว: ทองแช่ (เห็นด้วย). This process creates a flat surface crucial for modern components, protects the underlying copper, and provides a long shelf life.
ความหนาของทองแดง: 1ออนซ์ (approximately 35µm), a standard and robust weight that handles typical current loads in digital circuits effectively.
ความหนาสำเร็จรูป: 1.2มม, offering a rigid and durable board structure for most applications.
Critical Design Rules: Minimum Trace/Space of 6mil (0.15มม), enabling a good level of design density for complex digital circuits.
หน้ากากบัดกรี: 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:

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 พีซีบี กระบวนการ.
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 ต้นแบบ PCB and production inventory more manageable.
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.
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 การออกแบบ.
ความคุ้มทุน: 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.

The Manufacturing Workflow: A Glimpse into Precision Engineering

จากการออกแบบไปจนถึงการจัดส่ง

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

การเตรียมวัสดุ & การขุดเจาะ: The FR4 panel is prepared, and via holes are precision-drilled to create interconnections between layers.
Plating Through Hole (พท): A conductive layer is chemically deposited inside the drilled holes to establish electrical connectivity between the two sides.
Pattern Imaging & การพัฒนา: The circuit pattern is transferred onto the copper layers using photoresist and UV light.
การแกะสลัก: Unwanted copper is chemically etched away, leaving behind the desired circuit traces.
แอปพลิเคชันมาสก์ประสาน: The green or white solder mask is applied and cured, exposing only the component pads and vias.
การตกแต่งพื้นผิว – ทองแช่: The board undergoes the ENIG process, applying the nickel barrier and thin gold layer.
การพิมพ์ซิลค์สกรีน: Component designators and logos are printed on the board.
การทดสอบไฟฟ้า & การตรวจสอบขั้นสุดท้าย: 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 PCB สองด้าน, 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.
ตำแหน่งส่วนประกอบ: Place critical and noise-sensitive ส่วนประกอบ on one side (typically top) to simplify routing and minimize interference.
