Optimizing Smart Factory Process Control with True 3D Inspection Data


Continued from page 51 The­ combination­ of­ multi-


point­ measurement­ and­ process data­collected­from­SPI­and­pre- and­ post-reflow­ AOI,­ with­ the data­ from­ printers,­ placement systems­and­reflow­ovens,­is­nec- essary­to­achieve­an­AI-powered, zero-defect,­self-optimizing­line.


Inspection Feedback While­the­quality­of­data­is


more­ important­ than­ the­ raw quantity,­it­is­the­combination­of reliable­data­along­with­a­statis- tically­ significant­ quantity­ that delivers­ next-level,­ relatable results. A­ single­ inspection­ system


has­limits­and­cannot­manage­or optimize­an­entire­line.­Suppliers like­Koh­Young­have­tackled­this problem­ by­ collaborating­ in­ the industry­ to­ connect­ inspection systems­with­other­process­equip- ment,­such­as­printers­and­place- ment­machines.­Each­ individual company­ must­ also­ design­ and deliver­ suitable­ process­ controls for­ seamless­ communication across­ its­ own­ core­ set­ of­ equip- ment.­ Koh­ Young’s­ true­ 3D measurement­ data­ generated during­inspection­helps­to­identi- fy­ sources­ of­ inefficiency.­ Koh Young’s­LINK@KSMART­is­used to­deliver­multipoint­data­corre- lation­ and­ images­ from­ inline inspection­machines. The­ tool­ offers­ real-time


data­management­and­network- ing,­ providing­ operators­ with actionable­ insights­ to­ optimize processes.­ This­ feedback­ offers regular­data-based­review,­diag- nosis­ and­ optimization­ of­ print- ing,­ pick-and-place­ and­ reflow processes­with­linked­inspection results.
