Heavy copper PCB manufacturing services support 2-18OZ ultra-heavy copper, bump plating, embedded copper, and thermoelectric separation designs, ideal for high-current industrial, automotive, communication, and medical equipment requiring high heat dissipation and long-term reliability. Prototyping and mass production are available with no minimum order limits.
Overview
Heavy copper PCBs, also called thick copper PCBs, are specialized circuit boards with copper thickness exceeding 2OZ (70μm) on inner or outer layers, designed to address core challenges in high-power electronic systems including current overload, excessive heat accumulation, and mechanical stress failure. As core components for high-current, high-reliability electronic devices, heavy copper PCBs require precise manufacturing process control to ensure consistent current carrying capacity, thermal conductivity, and long-term operational stability. Professional heavy copper PCB manufacturing services cover the full production cycle from quick-turn prototyping for R&D verification to high-volume mass production for market deployment, adapting to custom design requirements across multiple industry scenarios with no minimum order quantity restrictions.
Technical Capabilities
- Wide Copper Thickness Support: Covers standard thick copper (2-10OZ) and ultra-heavy copper (10-18OZ) specifications, with optional bump-plated copper processing for localized high-current zones, improving targeted current carrying capacity without increasing overall board cost or thickness.
- Multi-Board Type Compatibility: Supports heavy copper integration across a full range of PCB types, including single-sided, double-sided, multilayer, high-frequency hybrid, rigid-flex, metal core, embedded copper block, and embedded component boards, adapting to diverse structural and performance requirements.
- Advanced Process Support: Equipped with mature processing capabilities including thermoelectric separation structure manufacturing, copper paste-filled vias, laser-drilled through holes, epoxy plug holes, peelable mask processing, and multiple surface finish options (hard gold, soft bonding gold, stepped gold fingers), meeting complex design demands for high-power systems.
- Flexible Production Scaling: No minimum order quantity requirements, with quick-turn prototyping lead times as short as 3-5 working days for small-batch R&D verification, and stable mass production capacity for 100k+ unit orders, ensuring consistent process quality across all production volumes.
Quality Standards
- Global Compliance Alignment: All manufacturing processes follow international industry standards, with full compliance with quality management system requirements for industrial, automotive, and medical electronics, ensuring products meet global market access regulations.
- Full-Process Testing Validation: All heavy copper PCBs undergo 100% electrical testing before shipment, with optional third-party testing services accredited to ISO/IEC 17025 standards, including thermal cycling testing, current load testing, insulation resistance testing, thermal conductivity testing, and EMC validation.
- Strict Process Control: Adopts high-precision production equipment including LDI laser direct imaging, X-ray non-destructive testing, and automatic optical inspection, achieving impedance control accuracy within ±10% for high-demand designs, and controlling copper thickness deviation within ±5% to ensure consistent performance.
- Wide Environmental Adaptability: Finished products support stable operation across an industrial-grade temperature range of -40°C to +85°C, with optional high-temperature and high-humidity resistance treatments to adapt to harsh operating conditions including vibration, corrosion, and extreme temperature fluctuations.
