Tripping side：
1. Automatic soldering technology for both sides, stable connection,and no false soldering.
2. Adopt chromium-free tin material, more green and environmentally friendly.
3. Double-layer thickened copper design, high flow, more stable.
Chip side：
1. Accurate parameters, every data is exactly the same as the actual product.
2. Use high-efficiency encapsulation chip design to improve heat dissipation performance and extend service life.
Mday signs partner agreement with EPCOS for next-generation surge，protective device's MOV development
