Blue ink double-sided spray solder PCB
Product Description
Blue ink double-sided spray solder PCB is a printed circuit board
that integrates blue solder mask with double-sided spray solder
(hot air solder leveling, HASL) surface treatment. It features a
double-sided wiring design, where the substrate is coated with blue
ink as the solder mask to insulate and protect the circuit, with
the distinct blue color aiding in identifying circuit areas. Both
sides of the board undergo spray solder processing: molten tin
alloy (lead-containing or lead-free) is evenly applied to the
exposed copper pads and leveled by hot air to form smooth, bright
tin layers. This board is suitable for small to medium complexity
circuits, accommodating the welding and assembly of conventional
through-hole and surface-mount components.
Core Characteristics
- Blue ink solder mask + double-sided spray solder combination: The blue ink provides stable insulation and clear visual differentiation of circuits, while the tin layers on both sides offer a reliable soldering base with strong adhesion.
- Double-sided wiring structure: Supports bidirectional signal transmission, adapting to the layout requirements of standard electronic devices and meeting small to medium-scale circuit design needs.
- Mature process compatibility: The integration of blue ink solder mask and spray solder is stable, with good material compatibility, fitting seamlessly into conventional production workflows.
Main Advantages
- Reliable soldering performance: The tin layers ensure excellent solder wetting, reducing the risk of cold solder joints and enabling multiple rework soldering, facilitating mass assembly and post-maintenance.
- Effective protection and identification: The blue ink solder mask isolates the circuit from external environments, enhancing corrosion resistance, while its distinct color simplifies production inspection and fault diagnosis.
- Cost-effectiveness: The mature spray solder process and blue ink application offer high production efficiency and controllable costs, making it suitable for cost-sensitive fields like consumer electronics, home appliances, and industrial control.
- Good environmental adaptability: Maintains stable performance in normal temperature, humidity, and general dust conditions, ensuring consistent operation over extended periods.
