Core Features of Double-Sided PCB (Black Mask & HASL)
| Category | Key Feature | Key Point |
|---|---|---|
| Structure | Layer Count | 2 layers (Top + Bottom) with PTH vias for interconnection. |
| Solder Mask | Color & Function | Black; insulates copper, prevents shorts, protects from environment. |
| Surface Finish | Type & Benefit | Hot Air Solder Leveling (HASL); cost-effective, good solderability. |
| Base Material | Substrate | FR-4 epoxy laminate; standard for general electronics. |
| Performance | Main Application Scope | Low-to-medium frequency; suitable for cost-sensitive, general-purpose devices. |
| Applications | Typical Products | Power supplies, LED drivers, small household appliances, industrial controls. |
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.
