Using the Taguchi Method to Determine Optimal Process Settings

LSI Logic worked with Particle Measuring Systems (PMS) to develop a machine that provides a repeatable, sensitive testing method. This machine, the Surfex™, uses a DI water recirculating filtration tank, coupled with ultrasonic transducers and a liquid particle counter. The tank is housed in an ISO Class 2 minienvironment.
This article discusses the characterization methodology used to determine the optimal process settings for various materials to be measured, and provides two examples of normal use investigations.
