Description:

Ultra-Large Copper-Clad Prototype Board for High-Density Circuits, Industrial Systems & Custom Hardware

The 12x18 inch general-purpose PCB board is one of the largest zero PCBs available for prototyping and is specially designed for industrial-scale electronics, full-system circuit integration, and professional-grade prototyping. Built with a 2.54mm standard grid, this board can accommodate thousands of through-hole components including ICs, sensors, power circuits, communication modules, and controllers.

Made from durable phenolic resin or high-performance FR4 epoxy laminate, it provides a rigid and heat-resistant foundation with tinned copper pads that allow efficient soldering and long-term durability.
