Demands for PCBs in Power Supply

Design Tips for Power Supply PCB

Power supply PCBs demand careful creepage and clearance design per safety standards, along with thick copper layers for high-current handling. Multi-layer stackups with dedicated power planes, optimized via stitching, and isolation slots minimize EMI and voltage drop. High-Tg materials and thermal management features ensure stable operation across wide input ranges in AC-DC and DC-DC converters.

Test Standards for Power Supply PCB

Power supply PCBs must meet UL 60950-1 / IEC 62368-1 safety requirements and IPC-6012 Class 2/3 qualification. Hi-pot, insulation resistance, and thermal cycling tests verify dielectric strength and long-term reliability. Burn-in and transient load testing ensure compliance under peak conditions for industrial and consumer power conversion systems.

Case Studies

Data Center Server PSU

The primary power conversion board in a 3kW server power supply uses a heavy-copper PCB to efficiently handle high-current 48V to 12V conversion with minimal losses and optimal thermal performance.

Telecom Rectifier Module

A power factor correction (PFC) board for a -48V telecom rectifier is built on a high-Tg FR-4 material, ensuring stable performance under continuous load and high-line voltage fluctuations.

FAQs of Power Supply PCBs

Q1: Why are heavy copper PCBs essential for high-current power supply designs?

A1: Because they provide superior current-carrying capacity and enhanced thermal endurance, preventing overheating and ensuring long-term reliability. AIVON utilizes specialized plating processes to achieve robust copper weights that withstand high power demands and thermal stress.

Q2: How to determine appropriate copper thickness for high-current DC/DC converters?

A2: For a high-current DC/DC converter, AIVON typically recommends a copper thickness between 2oz and 6oz, selected based on your specific current levels and thermal management requirements. We analyze your design's current density and thermal profile to determine the optimal thickness for efficiency and reliability.

Q3: How to select the right dielectric material for high-voltage power supplies?

A3: For high-voltage power supplies, AIVON specifies dielectric materials with high dielectric strength and a high Comparative Tracking Index (CTI) to ensure reliable insulation and prevent surface arcing. We assist in selecting the optimal laminate, such as specialized high-voltage FR-4 or polyimide, based on your specific operational voltage and environmental requirements.

Q4: What is the most effective via structure for thermal dissipation in compact power supplies?

A4: AIVON recommends utilizing copper-filled thermal vias and VIPPO (Via-in-Pad Plated Over) technology. This significantly enhances direct heat transfer from high-power components to internal ground planes, ensuring optimal thermal management.

Q5: Which surface finish provides the best solder joint reliability for heavy power components?

A5: AIVON recommends ENIG or Immersion Silver for power supply boards. These finishes ensure excellent coplanarity for large power modules, superior oxidation resistance, and exceptional solder joint durability under extreme thermal stress.
