Double-sided black oil spray solder PCB
Double-sided PCB, also known as double-sided printed circuit board, is a printed circuit board (PCB) with two-sided circuit connections. In this kind of PCB, the electronic components and circuit layout can be arranged on both sides of the PCB respectively, and the electrical connection of the circuits on both sides is achieved through vias (Vias). This structure greatly increases the functional density of the circuit board, allowing it to implement more circuit connections in a relatively small area.
Advantages of Double-sided PCB:
Main Features
1.Surface Finish
• Hot Air Solder Leveling (HASL) process
• Tin-lead alloy coating for enhanced solderability and reliability
Matte surface appearance
2.Solder Mask
• Black solder mask ink
• High contrast for better visual inspection
• Provides excellent protection for copper traces
• Cost-effectiveness
3.Economical manufacturing process
• Suitable for high-volume production
• Lower material and processing costs compared to other finishes
4.Applications
• Consumer electronics (e.g., smart home devices)
Industrial instruments
• Automotive electronics
• General-purpose PCB applications
5.Limitations
• Poor surface planarity
• Not recommended for fine-pitch components
• Lead-based process requires RoHS compliance
• Lead-free options available but at higher cost
