  • Company Overview: Camera Module Apple Vendor
  • Main job role is follow up NPI build and analysis failure module
  • ALE design DFM reviews & Machine retrofit with machine suppliers to improve the UPH& efficiency
  • Drive machine qualification including correlation, process capability (CP/CPK) and Gage Repeatability / Reproducibility (GR&R)
  • Improve SFR failure rate - The main cause that affects the SFR Score is assumed to be the Z-offset
  • ※ Z-offset (the focal length between the Lens and the Sensor).
  • - In order to simulate the SFR score select several Z-offset parameters, and prepare the sample in each Z-offset condition through DOE
  • And analyze the data and select the Z-offset for use in the AA process.
  • Through this DOE, can be determined appropriate process parameter, and make the low defect rate
  • Improve equipment vibration issue - The AF camera module is sensitive to vibration so it affects the test results.
  • - In order to prevent vibration of the factory floor, adding a Membrane Bi Airisolator to the equipment foot. research and found a suitable solution that is Bi Airisolator
  • - Change SW sequence ; Move VCM Test period to Handler non-running period
  • Improve equipment UPH - Divide the test zone from 1 site to 6 sites and all test zone testing together
  • - make a dual test site on each test zone so UPH is improved 2 times.
  • Camera Module Apple Vendor
  • Successfully develop the Fixed Focus and VCM Camera module
