Solder Resist for automotive application with outstanding reliability even in harsh environments
Solder Resist for automotive applocation with outstanding reliability even in harsh environments
Product Features
- In addition to conventional heat resistance, humidity, resistance, and insulation reliability, excellent crack resistance is achieved by the use of stress-relieving resin, which provides low elasticity and high elongation properties.
- Matte type
- High insulation resistance
- Good adhesion after high temperatures
- Thermal shock resistance
