• 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.
