Board Thickness : 1.5 mm to 1.6 mm

Copper Thickness Commonly 1 oz/ft² (approximately 35µm)

Surface Finish Bare copper (no solder mask or silkscreen applied by default for etching boards)

Flammability Rating : UL 94V-0 (self-extinguishing)

Operating Temperature : Up to approximately 140 °C for standard FR4

Features and Applications

• Prototyping & Education: This board is an ideal, cost-effective choice for general-purpose DIY circuit construction, soldering practice, and custom electronics development due to its simplicity and ease of etching, cutting, and drilling.
• Durable & Reliable: The FR4 material provides high mechanical strength, excellent electrical insulation, and resistance to moisture, ensuring the board's durability and structural integrity in both dry and humid conditions.
• Flame Retardant: The "FR" in FR4 stands for flame retardant, meaning the material will not sustain or spread a fire, which enhances safety in electronic devices.
• Wide Use: Single-layer FR4 PCBs are widely used in simple, low-density electronic devices such as calculators, LED lighting boards, simple power supplies, and consumer electronics where complex, high-frequency circuitry is not required.
