  Made from phenolic (cost-effective) or FR4 (high-performance) materials to withstand mechanical and thermal stress.

• Uniform Hole Drilling (~1mm diameter):
  Clean, consistent holes support reliable component installation and soldering.

•  Single-Sided / Double-Sided (depending on variant):
  For different levels of circuit design complexity.

• Customizable for Enclosure Mounting:
  Can be trimmed, drilled, or fixed inside large control boxes or cabinets.

Description:

Mega-Size Prototyping Board for High-Density Circuits, Power Systems, Automation, and Custom Electronic Designs

The 20x30 inch general-purpose zero PCB board is a super-sized prototyping platform tailored for high-end electronics development, large-scale industrial automation systems, and complex circuit integration. With a standard 2.54mm hole pitch grid and massive working area, this board allows for the design and testing of full electronic systems, multi-stage circuits, or panel-mounted solutions—all on one platform.

Constructed from durable phenolic resin or FR4 glass epoxy, and featuring pre-tinned copper pads, this board offers high thermal resistance, long-term durability, and superior soldering performance.
