5pcs 70x50mm Double Sided Copper Clad Laminate PCB Circuit Board FR4 1.5mm Thickness DIY Prototyping PCB Board

Size: 70mmx50mmx1.5mm

5pcs Double Sided Copper Clad Laminate PCB Circuit Board FR4 1.5mm Thickness Package Dimensions: ‎3.54 x 2.36 x 0.59 inches Material: FR-4 Glass Fiber with Copper. Layers: Double-sided. Includes 5 pieces of Copper PCB Board. Dimensions: 70x50mm / 2.76x1.97inch (Length x Width). Thickness: Approximately 1.5mm. Applications: Ideal for creating PCB circuit boards and prototypes. Commonly used in product development, DIY projects, maintenance work, and small-scale production. Features: Provides mechanical support and electrical connections for electronic components through conductive tracks, pads, and other features. These are etched from copper sheets laminated onto a non-conductive substrate. Note: The oxide layer on the copper-clad laminate surface should be polished clean using fine sandpaper. This ensures the carbon powder adheres firmly during the transfer process. The board surface should be polished to a bright finish.
