Material: Teflon Quality standard: IPC6012 Class 2 Dielectric constant: 2.65 Layers: 2Layers Thickness: 1.5mm Copper thickness: base copper 0.5oz, finished copper thickness 1oz Surface technology: Immersion Gold Application:Microwave high frequency PCB application Teflon PCB in high-end electronic products uses Teflon material. The scientific name of Teflon is polytetrafluoroethylene (PTFE). This material is resistant to acids, alkalis and various organic solvents, and is almost insoluble in all solvents. At the same time, Teflon material has the characteristics of high temperature resistance, and its dielectric coefficient is very low, so it is an ideal high frequency
