This heavy copper 2oz single layer PCB board is engineered for power-hungry, single-sided designs that demand real current-carrying headroom. Where conventional 1oz foil begins to warm under sustained load, the thicker conductor used here lowers trace resistance and spreads heat across the plane, keeping power components comfortably cool. Built on a rigid FR-4 base with lead-free HASL coating, it combines dependable solderability with environmentally responsible processing.
Key Features
Heavy 2oz Copper Conductor: Thicker copper foil reduces voltage drop and self-heating, allowing higher continuous current through narrow traces
Single Layer Simplicity: One conductive layer simplifies routing, assembly, and maintains predictable unit costs from prototype to volume production
Lead-free HASL Finish: RoHS-compliant tin coating prevents oxidation and accepts both manual soldering and automated reflow processes
Enhanced Heat Dissipation: Expanded copper area moves thermal energy away from hot spots, improving operating life of LEDs and switching devices
Fast Prototype Support: Streamlined CAM review and quick-turn tooling enable rapid engineering sample delivery for functional validation
Flexible Build Options: Customizable board thickness, copper weight, mask color, and outline to fit specific enclosure and mounting requirements

Applications
Heavy copper single layer boards are ideal for LED driver modules where higher current and continuous operation require superior thermal management. They serve input and output stages of switching power supplies, battery chargers, and small motor drivers, benefiting from reduced resistance of thicker foil. In industrial and commercial equipment, this construction supports relay boards, sensor interfaces, and control panels designed for cost efficiency and clarity. The generous copper weight is particularly valuable in sealed housings where limited air circulation requires heat conduction through the board itself.
Packaging & Quality Assurance
Finished boards undergo cleaning, electrical testing, and automated optical inspection before being sealed in anti-static vacuum bags with desiccant to protect surface finish during transport. Export-grade corrugated boxes prevent flexing in transit. Standard lead time is 8-15 working days for production, with faster turnaround available for prototype quantities. Each shipment includes electrical test reports and material declarations, with technical support available for gerber data review and recommendations on copper weight or finish options for specific current loads.
