Product: DoubleSided PCB Board Key specifications Hole Dia (Each): 1 mm Hole Pitch: 2.54 mm (0.1 in) Total Size: 4 x 6 cm (1.6' x 2.4') W x L Mounting Hole Dia.: 2 mm (0.08 in) Thickness: 1.6 mm Materials: PCB, Tin Plated, Glass Fiber Main Color: Green, Silver Tone Why this board serves your needs Higher circuit density: Doublesided design enables more complex and compact layouts compared to singlesided boards. Reliable solderability: Tin plated finish improves solder flow and helps resist corrosion for durable connections. Sturdy substrate: Glass fiber construction provides rigidity and stable electrical performance. Standard alignment: 2.54 mm hole pitch aligns with common throughhole components and 0.1 inch headers for easy prototyping. Compact footprint: Sized for small projects while still offering practical mounting and wiring options. Use scenarios Prototyping small electronics projects that use throughhole components and 0.1' headers Educational electronics kits and classroom experiments requiring reliable doublesided boards Mounting sensors or compact modules in small enclosures or panel assemblies where precise hole spacing and mounting options are needed
