RF-35 is the best choice for low cost, high volume commercial microwave and radio frequency applications. RF-35 has excellent peel strength for 1/2 ounce and 1 ounce copper (even in comparison to standard epoxy materials), a critical aspect whenever rework is required. RF-35’s ultra low moisture absorption rate and low dissipation factor minimize phase shift with frequency.
