Siti Ainul Afifah Osman
AOI & SPI Engineer @ Hotayi Electronic
About
A Master’s degree in Industrial Engineering has been earned, supported by over four years of experience in the semiconductor and electronics manufacturing industry. Exposure has been gained in SMT process support (AOI & SPI), production supervision, and Lean Manufacturing practices. Various improvement initiatives have been implemented, including 5S projects and inspection system optimization, leading to increased efficiency and product quality. Technical issues have been addressed using structured problem-solving tools such as DMAIC, Fishbone Diagrams, and 5 Whys. Analytical tools like SPSS and MINITAB have been utilized in both industrial and research settings. A postgraduate research project on the interrater reliability of a health risk assessment tool was completed, demonstrating a strong focus on data accuracy and standardization. Currently, new opportunities are being sought in Quality, Manufacturing, R&D, or Failure Analysis within a global MNC environment, where past experience and skills can be applied toward continuous improvement and operational excellence.
