Double-Sided Power PCBs: 信頼性のある, High-Current Boards for Demanding Applications
In an era of high-power electronics, stable and efficient power management is critical. あ プリント基板 (プリント基板) optimized for power transmission and conversion is often the cornerstone of system reliability. Our double-sided power PCBs are engineered to meet the stringent challenges of high current, voltage, および熱管理.

製品の概要: What is a Double-Sided Power PCB?
A double-sided power PCB is a specialized printed circuit board designed to carry and distribute high current and manage substantial power across its two layers. Unlike standard signal PCBs, its core design objectives are low impedance, high current-carrying capacity, and superior thermal performance. We use FR-4 (a flame-retardant glass-reinforced epoxy laminate) as the base material, ensuring every board performs reliably in applications like power converters, motor drives, and industrial power supplies through stringent process control.

Design Essentials & 作業原則
Key Design Considerations:
-
Wide Traces & 重い銅: Power paths (例えば。, Vin, Vout, GND) use the widest possible traces with 1oz or thicker copper to minimize resistance, heat generation, and voltage drop.
-
Adequate Via Stitching: Multiple vias in arrays are used to connect the same power net on both layers, significantly reducing parasitic resistance and inductance of the vias and enhancing current capacity.
-
熱管理: Strategic placement of heat-generating components (例えば。, MOSFET, インダクタ) alongside thermal vias そして exposed copper pads to efficiently transfer heat to the opposite side or an external heatsink.
-
Safety Spacing: Electrical clearance and creepage distances for high-voltage lines are strictly set according to safety standards (例えば。, UL, IEC) to ensure operational safety.
作業原則:
The double-sided power PCB serves as a passive interconnection platform. Its function is to provide optimal electrical and physical connections for active power コンポーネント (IC, 変圧器, コンデンサ, インダクタ). Through meticulously designed high-power traces, it ensures energy is transferred from input to conversion circuitry and then to the load with minimal loss and heat generation. Effective thermal path design keeps component junction temperatures within safe limits, enabling reliable PCBAアセンブリ and long-term stable operation.
