Abstract
The novel idea of an orthogonal fuzzy rule-based system is introduced in this paper. It is shown that in a fuzzy rule-based system where rules are orthogonal, each rule induces its maximum effect on the final decision. Using 18 orthogonal fuzzy rules, a model for the solder paste printing stage of SMT is created. The predicted percentage of deposit volume from the orthogonal and non-orthogonal models are compared with actual values. The orthogonal model shows less error in 85% of the data points.
