Solder Mask
- LPI (Liquid Photo-Imageable) solder mask; primarily green, with black, blue, and white options available.
- Features uniform thickness, high dielectric strength, and resistance to moisture and scratching.
- Precise solder pad openings; via plugging available to prevent short circuits.
Design & Manufacturing Advantages
- Rapid Prototyping: Small batches with short lead times (24–72h), ideal for prototype validation.
- Low Cost: Double-sided FR4 technology is mature and cost-effective.
- High Flexibility: Trace widths, spacing, and hole locations follow the design; supports rapid iteration.
- Manufacturability: Standard CNC drilling/milling, HASL or ENIG finishes, and flying probe testing.
- DFM-Friendly: Validate designs and functionality before transitioning to mass production.
Applications
- New product prototype verification and functional debugging
- Small-batch trial production; test boards / fixture boards
- Education / scientific research and project validation
- Consumer electronics, simple industrial control circuits, and power modules
