    Hi all,Actually, I am working on a project for optimizing the response of certain microelectronic device. This device is assembled with several passive components (capacitors), so that I would like to run a DOE for screening the main factors (most of them are continuos variables)using a Placket-Burnam design and then to run another one for find the optimal value from the main factors using a full factorial level III. Do you recommend using any other model for screening & optimizing the response of this circuit? Any comment is welcome,

    Miguel,
    A PB design is certainly the way to go for a screening DOE, but it depends on the number of main effects that you want to study.  If you have 6 or 7 factors that you want to study, then a 8-run PB is the way to go.  Remember a 8-run PB is a resolution III design with a complex alias structure.  To increase your design resolution (IV), it is a good idea to “fold” your design as a follow up experiment (another 8-run PB).  This foldover will clear up the picture as to how main effects are affected by your design (i.e separating main effects from 2 factor interactions).  If you have only have 3-5 factors to study, you may get a lot more value out of doing a full factorial or fractional factorial depending on how much it costs to setup and conduct your experiment.
    I hope that helps a little.

    Hi all,If anyone can share any information for a SS project tending to optimize the response from an electrical circuit will be great.BR,

    Miguel,What characteristics would you like to optimize on your circuit?

    I would like to optimize the Power out & the efficiency (Pout/Pin).
