What are the Trade-Offs Between Halogen-Free FR4 and Standard FR4?

The trade-offs between halogen-free FR4 sheet and standard FR4 primarily revolve around environmental impact, flame retardancy, and performance characteristics. Halogen-free FR4 offers improved environmental friendliness and reduced toxicity during disposal or recycling, addressing growing concerns about the environmental impact of electronic waste. However, it may exhibit slightly different flame retardant properties compared to standard FR4, which has long been the industry norm. Standard FR4 typically provides excellent flame retardancy and established performance metrics, but faces scrutiny due to potential environmental concerns associated with halogenated compounds. The choice between these materials often depends on balancing regulatory compliance, environmental considerations, and specific application requirements in the electronics industry.
