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.
