Product Description
Black oil spray tin double panel PCB
Product Description
Black oil spray tin double panel PCB is a double-sided printed circuit board integrating black solder mask and double-sided spray tin (hot air solder leveling, HASL) surface treatment. It adopts a double-sided wiring design: the substrate (usually standard FR-4) is coated with black ink as the solder mask, which provides insulation, protects the circuit, and offers excellent light-shielding properties. Both sides of the board undergo spray tin processing on exposed copper pads—molten tin alloy (lead-containing or lead-free) is evenly applied and leveled by hot air to form smooth, bright tin layers. This PCB is suitable for small to medium complexity circuits, adapting to the welding and assembly needs of conventional through-hole and surface-mount components in general operating environments.
Core Characteristics
- Black oil solder mask + double-sided spray tin combination: The black ink ensures stable insulation, strong light-shielding, and a professional appearance; the tin layers on both sides provide a reliable soldering base with good adhesion and uniform thickness.
- Double-sided structure: Supports bidirectional signal transmission, meeting the layout requirements of standard electronic devices and small to medium-scale circuit design needs.
- Process compatibility: The integration of black oil solder mask and spray tin is stable, with good material compatibility, fitting seamlessly into conventional production workflows.
Main Advantages
- Reliable soldering performance: The tin layers enable excellent solder wetting, reducing the risk of cold solder joints and allowing multiple rework soldering, facilitating mass assembly and post-maintenance.
- Superior light-shielding and protection: The black solder mask effectively blocks light interference in sensitive circuits and isolates the board from external environments, enhancing corrosion and abrasion resistance.
- Cost-effectiveness: The mature spray tin process combined with economical black ink and standard substrates results in controllable production costs, suitable for cost-sensitive fields like consumer electronics, home appliances, and industrial control.
- Mechanical robustness: The tin layers form strong bonds with components during soldering, improving resistance to vibration and mechanical stress, making it suitable for devices subject to physical impact.
- Good environmental adaptability: Maintains stable performance in normal temperature, humidity, and general dust conditions, ensuring consistent operation over extended periods.
