Solder mask characteristics
- LPI (Liquid Photo-Imageable) solder mask—primarily green, with other colors available;
- Uniform thickness, high dielectric strength, and resistance to moisture and scratching;
- Precise solder mask openings; via plugging available to prevent short circuits.
Design and Manufacturing Features
- Multi-layer solid power and ground planes supporting controlled impedance;
- CNC drilling and routing, HASL / ENIG finishes, and flying-probe / impedance testing;
- Panelization with V-scoring / tooling strips, suitable for mass production;
- High-Tg materials for high-temperature resistance and reliability across a wide temperature range.
Application scenarios
The vast majority of electronic products, including consumer electronics, industrial controls, communication equipment, power modules, automotive electronics, medical equipment, and industrial automation systems.
