Applying Gauge R&R for Soldering Optimization

摘要

Before starting an optimization process, be sure the measurement system is accurate and precise. Accuracy is defined as absence of bias in the measurement and precision as the dispersion of the measurements. To quantify precision, a gauge study can be used. Sources of dispersion are failure of the measurement instrument or gauge to exactly repeat itself (repeatability) and failure of the operator or machine to exactly reproduce the measurement technique (reproducibility).
