General Purpose Solderable Board FR2 A Grade Material (140 mm * 90 mm)

The General Purpose Solderable Board (140 mm x 90 mm), often referred to as a "Perfboard" or "Zero PCB," is a blank, single-sided prototyping board widely used for building and testing electronic circuits. Made from FR2 A-grade material (Phenolic resin/synthetic resin bonded paper), it provides an affordable, rigid, and electrically insulated foundation for components. Unlike standard breadboards, this board requires components to be soldered into place, offering a more permanent and durable solution for DIY electronics, school projects, and rapid hardware prototyping. The copper pads on the board are typically laminated or lacquered to prevent corrosion and facilitate easy, reliable soldering.
