Hi suganthi
Dicy-cured FR-4 materials are traditionally composed of woven-glass
reinforcement materials and an epoxy resin with a
dicyandiamide (dicy) cure agent, dicy-cured FR-4
materials are commonly used in processes that use
Tin-Lead-based solder, such as automated-wave,
hot-air or hand-soldering assembly techniques.
Non-dicy resin technology in FR-4 or other resin laminates is
not new, even if dicy has been the preferred cross-linking
agent for many resin laminates. Non-dicy FR-4 laminates
have been aggressively investigated and marketed for several
years due largely to their improved thermal performance.

Thanks
