Product Description
Heavy Copper PCB Overview
Ring PCB provides comprehensive PCB & PCBA turnkey solutions with professional circuit manufacturing expertise.
What Are Heavy Copper PCBs?
Heavy copper PCBs (also known as thick copper or power PCBs) feature significantly thicker copper layers ranging from 3 oz/ft² to 20 oz/ft² or more. Compared to standard PCBs with less than 2 oz/ft² copper thickness, these boards offer enhanced current-carrying capacity for high-power applications.
Key Advantages
- Improved Signal Integrity: Minimizes signal loss and distortion for clear, accurate data transmission in telecommunications and data applications
- Lower Dielectric Loss: Utilizes materials with low dielectric constants to reduce energy loss in high-speed environments
- High Thermal Stability: Withstands elevated temperatures without degradation for demanding applications
- Precise Impedance Control: Maintains signal quality and minimizes reflections in RF and microwave applications
- Excellent EMC: Minimizes electromagnetic interference while enhancing signal integrity
Custom Design Capabilities
Ring PCB customizes all types of PCB boards with flexible layer structures, material selection, and form factors to match your specific product requirements.
Sample production completed within 7 working days, with mass production and delivery within 15 working days.
Manufacturing Expertise
Advanced Etching Process
Utilizes controlled chemical etching and temperature management to achieve uniform copper traces for thicknesses up to 20 oz/ft².
Thermal Management
Implements temperature control and gradual thermal cycling throughout manufacturing to prevent warping and delamination.
Precision Drilling
Employs high-precision drilling machines and specialized drill bits designed for thick copper layers.
Copper Plating Technology
Uses chemical and mechanical roughening followed by copper plating to ensure uniform coverage and strong bonding.
Hole Size Compensation
Calculates initial drill size based on plating thickness to maintain final hole dimensions.
Applications
- Automotive Electronics: Electric vehicles, power converters, braking systems
- Aerospace & Military: Equipment requiring reliability in extreme environments
- Power Supplies: Uninterruptible power supplies (UPS) and high-power devices
- Renewable Energy: Wind turbines and solar power systems
- Industrial Equipment: Heavy-duty machinery, motor controls, power distribution units
