You may have heard talk in the news lately regarding counterfeit electronic components making it into the US military supply chain. The U.S. Senate Armed Services Committee (SASC) recently reported in the Counterfeit Electronic Parts in the Defense Department Supply Chain hearing held on November 17, 2011, 1,800 cases of suspected counterfeit components that went into more than 1 million individual products. If you consider this number for the military, we can only imagine the number of counterfeits in our commercial yet high reliability products, such as life support or other critical systems. If you are the person within your electronics-based company who must perform risk analyses, counterfeiting is not a new concern, yet many do not realize just how good counterfeiters have become at their "trade".

Imagine being able to accurately predict the correct artwork compensations prior to taking on a large quick turn order regardless of the board design, materials, or process. Such predictive power is possible and can be achieved without a lot of cost and complexity. This paper shows how small sets of designed experiments can be used to create a cImagine being able to accurately predict the correct artwork compensations prior to taking on a large quick turn order regardless of the board design, materials, or process. Such predictive power is possible and can be achieved without a lot of cost and complexity. This paper shows how small sets of designed experiments can be used to create a compensation model. Before a discussion of the design of experiments (DOEs), we will examine key processes and material variables that affect movement as demonstrated on real board design layout in a real production process. Only the few most relevant variables need to be included in the experimental design. A solution is presented that uses small experiments that provide the required information for constructing a general compensation model.mpensation model.
