Product Overview

Heavy copper etching plated printed circuit boards (PCBs) are designed to handle high current and to improve thermal management in electronic circuits. Heavy coppe PCBs feature thicker layers of copper compared to standard PCBs, which enhances their ability to conduct higher currents and dissipate heat more effectively. Heavy copper PCBs are widely used in power electronics, automotive, aerospace, and industrial applications where reliability and performance under high power conditions are critical.

Key Features:

High Current Handling:With thicker copper layers, these PCBs can carry higher currents without overheating.

Enhanced Thermal Management:Superior heat dissipation capabilities ensure stable performance in high-power applications.

Durability: Increased mechanical strength and resistance to thermal cycling and physical stress.

Precision Etching:Advanced etching techniques ensure high accuracy and clean edges, even with thick copper layers.

Versatility:Suitable for a wide range of applications, from power supplies and converters to motor controllers and industrial equipment.
