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.
