76 PCB007 MAGAZINE I MAY 2018 Sainsbury reviewed the role of data in the Smart Factory Initiatives. His example is the current Whelen green factory. This takes dis- connected data from various factory sources including: • Pilot batches • Cross-section analysis • Look-up tables • X-Ray drill optimizers • Coordinate measurement machines • AOI inspection It is collected and analyzed to correct for scale errors or misalignment of layers within the panel and adjust the drill program for min- imum mis-registration. This process is shown in Figure 14. Analysis of X-ray data is seen in Figure 15. In addition to the AOI data of innerlayers and lamination effects, these measurements allow for compensation of drilling program and di- rect digital exposure. Coordinated analyzed data leads to better control actions and future results, as seen in Figure 16. Sixth Presentation The sixth presentation of the seminar was on "HDI Chemical Process Control and Analy- sis" given by myself.
