Research Progress of Halogen-free Flame Retardant Epoxy in Electronic Packaging

The work aims to review the latest research progress of halogen-free flame retardant epoxy and provide research ideas and technical guidance for the development of high efficient flame retardant packaging materials. The types and mechanism of halogen-free flame retardant epoxy were introduced by literature survey, the application status and technical progress of halogen-free flame retardant epoxy in electronic packaging were summarized, and the future development trend was prospected. Compared with the intrinsic and reactive halogen-free flame retardants, the filled halogen-free flame-retardant epoxy had the advantages of simple process, complete variety and high performance, it was the most widely used halogen-free flame retardant epoxy.Halogen-free flame epoxy could effectively enhance the fire safety of electronic packaging materials, extend the service life of electronic devices and promote the rapid development of 5G electronic devices.
