Try to design PCB stackup by yourself
Basic information about PCB stackups:
PCB is build from three basic materials: Copper foil, Prepreg, Core
Standard Copper foil thickness: 5um, 12um, 18um, 35um, 70um
Standard prepreg thickness: 65um, 100um, 180um
Standard core thickness: 0.15mm, 0.20mm, 0.36mm, 0.46mm, 0.56mm, 0.71mm, 1mm, 1.2mm, 1.5mm, 2.0mm, 2.4mm, 3.2mm. Core is supplied with copper foil on both sides. For some cores you need to add copper foil thickness (18um or 35um) to the core thickness.
