A pre-production manufacturability review checks that your stackup, dielectric thicknesses, line widths, and via design are buildable and consistent with your impedance targets – the place where many RF boards either succeed or develop problems. When requesting a quote, specify the exact laminate (RO4003C or RO4350B), standard or LoPro foil, your operating frequency, your target impedance, and the stackup. When that grade is chosen, RO4003C board construction after material selection connects the datasheet decision with the released stackup and manufacturing drawing.
