• Combination of double-sided HASL and red oil solder mask: The tin layer provides a welding base with strong adhesion and a bright surface; the red solder mask ink has a vivid color, stable insulation performance, and both protective and identification functions.
• Double-sided wiring structure: Supports two-way signal transmission, adapts to the circuit layout needs of standard electronic equipment, and the wiring space meets the design requirements of small and medium-sized circuits.
• Mature process adaptability: The combination of the HASL process and the red oil solder mask is stable, and the ink has good compatibility with the substrate and tin layer, which can adapt to conventional production processes.
Reliable welding performance: The tin layer ensures good wetting of the solder, reduces the risk of cold solder joints, and supports multiple welding operations, facilitating mass assembly and later maintenance.
Clear identification and protection: The red solder mask can intuitively distinguish circuit areas, making it easy for production inspection and fault diagnosis; at the same time, it effectively isolates the copper surface from the external environment, improving corrosion resistance.
Balance between cost and practicality: The HASL process is mature with high production efficiency, and combined with the economy of red oil solder mask, the overall cost is controllable. It is suitable for fields such as consumer electronics, home appliances, and industrial control that are cost-sensitive and require basic identification functions.
Good environmental adaptability: The combined effect of the tin layer and the red oil solder mask enables the circuit board to maintain stable performance in normal temperature, normal humidity, and general dust environments, extending its service life.
