5CM x7CM Copper Clad Single-sided Board

A 5cm x 7cm copper-clad single-sided board is a small, versatile electronic base material (Copper Clad Laminate or CCL) made from fiberglass (FR4) with a copper layer on just one side, perfect for DIY electronics, prototyping, and learning soldering, offering good mechanical/dielectric properties for small projects like musical instruments or simple circuits. 
Key Features & Uses
Material: Typically FR4 (glass fiber reinforced epoxy resin) for durability.
Size: Small, 5cm by 7cm (about 2x3 inches), ideal for compact designs.
Type: Single-sided (copper on one face only).
Applications: Product development, DIY electronics, experiments, creating custom circuit boards, and even small mechanical parts.
Properties: Good flatness, bending strength, heat resistance, and moisture resistance.
