54 DESIGN007 MAGAZINE I APRIL 2025 Feature Interview by Andy Shaughnessy I-CONNECT007 e RF materials arena has changed quite a bit in the past decade. e newest thermoset laminates boast performance numbers that are almost competitive with PTFE, but without the manufacturability challenges. At IPC APEX EXPO this year, I spoke with Brent Mayfield, business development man- ager at AGC Multi Material America. Brent walked through some recent innovations in RF materials, advances in resin systems, and the many design trade-offs for RF engineers to consider for each material set.
