5oz Heavy Copper Dual Sided PCB IPC-A-610 D Standard

• PCB layer: 2
• PCB size: 15*12CM
• Base material: Rogers 4003
• Surface finish: ENIG

Conventional double-sided circuit boards typically have a copper thickness of 1oz, while multi-layer boards generally feature 0.5oz inner layers and 1oz outer layers. Boards exceeding 1oz copper thickness are classified as thick copper circuit boards.

The primary manufacturing challenges for heavy copper PCBs include:

• Line width requirements increase proportionally with copper thickness to prevent etching issues
• Potential for uneven copper surfaces if plating processes aren't precisely controlled
• Higher process requirements and manufacturing complexity

• Superior heat dissipation capabilities
• Higher current carrying capacity
• Enhanced product stability
• Extended product lifespan

These specialized PCBs are essential for:

• Transportation systems (automotive electronics, rail traffic control)
• Medical instrumentation
• Aerospace technology
• Industrial control systems

While most PCB manufacturers cap copper thickness at 1.5-2oz, advanced facilities can produce boards with up to 6oz (210μm) copper thickness.

• Increased circuit density: Accommodates more components in compact designs
• Enhanced functionality: Supports complex circuitry with through-hole and SMT components
• Improved signal integrity: Reduced EMI through ground/power planes
• Design flexibility: Efficient space utilization with components on both sides
• Cost-effective: More economical than complex multi-layer boards

• Consumer electronics (smartphones, tablets, TVs)
• Industrial control systems and automation
• Automotive electronics (ECUs, infotainment systems)
• Medical diagnostic and monitoring equipment
• Telecommunications infrastructure
• LED lighting systems
