Black oil OSP 4-layer board PCB is a 4-layer printed circuit board that combines black solder mask, OSP (Organic Solderability Preservative) surface treatment, and a multi-layer wiring structure. The substrate (typically FR-4) consists of four conductive layers, interconnected by plated through-holes to enable complex signal transmission. The board is coated with black ink as the solder mask, providing insulation, circuit protection, and excellent light-shielding properties. Exposed copper pads on all layers undergo OSP treatment, forming a thin organic protective film through chemical reactions to prevent copper oxidation while maintaining solderability. This PCB is suitable for medium-complexity circuits, adapting to the welding needs of precision components like SMT and fine-pitch parts in general operating environments.
Core Characteristics
4-layer structure + black oil solder mask + OSP treatment: The 4-layer design offers ample wiring space for medium-complexity circuits; the black ink provides stable insulation, strong light-shielding, and a professional appearance; the ultra-thin (0.1-0.3μm) OSP film ensures oxidation resistance and reliable solderability on copper surfaces.
Interconnected layers: Plated through-holes enable electrical continuity between the four layers, supporting complex signal routing and power distribution.
Process compatibility: The integration of 4-layer lamination, black oil solder mask, and OSP treatment is stable, with good material compatibility, fitting into standard production workflows.
Main Advantages
Enhanced wiring capacity: The 4-layer structure allows separate power, ground, and signal layers, reducing crosstalk and improving signal integrity, suitable for medium-complexity circuits in communication devices and industrial control systems.
Reliable solderability: The OSP film is easily removed during soldering, ensuring good solder wetting on copper surfaces, minimizing cold solder joints, and adapting to precision components like QFP and BGA.
Superior light-shielding and protection: The black solder mask effectively blocks light interference in sensitive circuits and isolates the board from external environments, boosting corrosion and abrasion resistance.
Cost-effectiveness: Compared to higher-layer boards, the 4-layer design balances performance and cost; combined with low-cost OSP and economical black ink, it offers controllable production expenses, suitable for cost-sensitive mid-complexity applications.
Environmental friendliness: The OSP process uses non-toxic organic compounds, and the black ink is generally eco-friendly, complying with environmental regulations and reducing hazardous waste.
Dimensional precision: The thin OSP layer and black ink do not significantly affect the board’s thickness or flatness, maintaining precision for high-density 4-layer circuit designs.
