Cost Effective Design for Six Sigma in Component Placement

The size decreison of passive components nowadays reaches 01005 dimension. For larger components also, but for these tiny components the accuracy of the component placement machines is a very important variable in respect of the placement quality. There are other variables that affect the placement quality (the quality of the solder paste, or the adhesive etc.), but I only studied the methods, that could improve the accuracy of the placement machines. It was a very important aspect that I use the method that is suggested in the standard: IPC-9850, but not to use expensive, special optical CMM (Calibrated Measuring Machine), and not to use expensive tester components (QFP, R, C, etc.) either.
