The prepreg(PP) is the material that must be used to make multilayer PCB which is a sheet material composed of a resin and a carrier.
Rogers RO3003 & RO3010 laminates have a lower Dk value of 3.00 (± 0.04), its TCDk is also much lower (Z-trend -3 ppm/°C). TMM materials are an exception. Although TMM materials have very high Dk values, such materials still have lower TCDk values.
