Heat-resistant solder resist ink "HRS-1-7W"
Resistant to high temperatures, ultraviolet rays, and chemical environments! A next-generation solder resist ink that combines functionality and reliability.
This product is a high-performance resist ink based on silicone, featuring excellent heat resistance and UV resistance, as well as advanced measures against low molecular siloxanes. It shows minimal discoloration and cracking even under heating and UV environments, making it ideal for coating applications in electronic and electrical components that require high reliability. Particularly, after heat treatment at 320°C for 2 minutes, there is very little change in reflectivity, and no discoloration or cracking is observed (refer to graphs and images). Additionally, even after 2,000 hours of exposure to UV-C (265nm), it maintains a high reflectivity, demonstrating stable performance in deep UV environments. Furthermore, it suppresses the generation of low molecular siloxanes (cyclic siloxanes (D4 to D10)), which can cause contact failures. It can be safely used in clean environments and in situations where the reliability of electronic device contacts is required.
