RF-30A Technical Properties for PCB Engineering
The following selected properties provide a practical reference for RF-30A PCB stack-up planning and fabrication review. Material values describe the laminate itself and should not be interpreted as guaranteed electrical performance of a finished PCB.

Remarks
- The values above are typical laminate reference data and may vary with material construction, copper configuration, processing conditions, and test method.
- Current AGC documentation lists RF-30A as the applicable product designation. Material availability, thicknesses, copper options, and specification limits should be confirmed using the latest documentation from AGC.
- Material-property values should not be interpreted as guaranteed RF, impedance, insertion-loss, or PIM performance of a finished PCB or electronic assembly.
RF-30A PCB Fabrication Considerations
RF-30A PCB manufacturing requires process controls that differ from conventional epoxy-based circuit boards. The PTFE-containing material system, woven-glass reinforcement, RF copper geometry, plated-hole requirements, and dimensional behavior all need to be considered when developing the fabrication route.
- Dimensional control: Panel handling, copper distribution, laminate thickness, and artwork compensation should be considered when tight RF registration is required.
- Drilling: Drill condition, feed, speed, stack height, and fiberglass structure can influence hole-wall quality and finished plated-hole dimensions.
- Hole-wall preparation: PTFE-containing drilled surfaces require an appropriate preparation process before metallization and copper plating.
- Multilayer bonding: Registration and the condition of the bonding surface should be reviewed when RF-30A is incorporated into multilayer or hybrid PCB constructions.
- Copper and RF geometry: Finished copper thickness, conductor profile, dielectric spacing, line width, ground structure, and transitions should be evaluated together for controlled-impedance RF circuits.
- Surface finish and solder mask: The selected finish and solder-mask construction should be considered in relation to exposed RF features and the electrical requirements of the circuit.
Highleap Electronics develops the PCB production route from the released Gerber data, material callout, stack-up, impedance requirements, drilling information, and mechanical drawing rather than applying one generic process to every RF-30A design.
