36 SMT Magazine • June 2017 cellent attribute gage R&R for appraisers agree- ment percentage. For the agreement for each appraiser versus standard percentage: AOI Sys- tem 1's result is OK; both AOI System 2 and Sys- tem 4 have good results. AOI System 6 has very good results, while AOI System 5 has excellent results. AOI Testing Results A total of 1,230 components on the five boards were tested for this project on different AOI machines, where AOI 1 is 2D AOI, the rest have 3D AOI capabilities. However, 3D was not used in this stage of the study. The main two items (defects escaped %, and false call PPM) were used to evaluate each AOI machine's test capabilities. The defective component location is confirmed by engineers of the company and the AOI Suppliers based on the AOI images, op- tical pictures, and optical metrology equipment. Figure 5 is the picture from the optical metrol- ogy equipment. It is clear to see that compo- nents R1, R6, and R7 are misaligned as defects; AOI CAPABILITIES STUDY WITH 03015 COMPONENTS Figure 4a: AOI 1 GR&R. Figure 4d: AOI 4 GR&R. Figure 4f: AOI 6 GR&R.
