Product Definition and Structure
What is a Double-Sided PCB?
A double-sided PCB is a printed circuit board with conductive copper layers on both sides of the substrate, allowing circuits on the top and bottom to be interconnected through vias or plated-through holes. This design significantly enhances PCB routing flexibility, making it suitable for moderately complex electronic devices. UGPCB’s double-sided PCB employs a 2-layer structure combined with an Immersion Gold surface finish, ensuring excellent conductivity and corrosion resistance, making it an ideal foundation for PCBA.
Structural Composition
The structure of UGPCB’s double-sided PCB comprises the substrate, copper layers, solder mask, and surface finish layer. The substrate utilizes FR-4 material, a glass-reinforced epoxy laminate known for its good mechanical strength and electrical insulation. The copper layers, with a thickness of 1 أوقية (approximately 35μm), are distributed on both sides and interconnected via drilling and plating processes. The surface finish employs Immersion Gold technology to enhance solderability and oxidation resistance. With an overall thickness of 1.6mm, this PCB ensures stability and durability, catering to high-density PCB applications.
Key Design Considerations for Double-Sided PCBs
When designing double-sided PCBs, particular attention must be paid to trace width and spacing parameters. UGPCB’s product offers a minimum trace width and spacing of 6 ميل (0.15مم), facilitating high-density routing while mitigating signal interference and short circuits. Designers should also consider thermal management and impedance control to ensure stable PCB performance during PCBA assembly. بالإضافة إلى, the Immersion Gold surface finish necessitates optimized pad layouts to improve solderability and reliability. For applications like adapter PCBs, using professional تصميم ثنائي الفينيل متعدد الكلور software to simulate circuit performance is recommended to minimize production errors.
Working Principle of Double-Sided PCBs
The operational principle of double-sided PCBs is based on circuit interconnections on both sides of the substrate, transmitting electrical signals and power through conductive vias. As current flows through the copper traces, the PCB acts as a carrier, connecting various electronic components to achieve specific functions. على سبيل المثال, in adapter PCBs, the double-sided design allows power management circuits to be distributed on both sides, improving efficiency and thermal performance. The Immersion Gold surface finish ensures low resistance at contact points, extending the PCB’s lifespan. The entire process relies on high-quality PCBA to integrate the PCB with components, forming a complete electronic system.
