Defect-Analysis-of-Electric-Circuit-Boards-using-Statistical-Process-Control-SPC-for-Quality-Mgmt.

  • This project is about considering a hypothetical company which manufactures Electric Circuit Boards (ECB).
  • During the quality control the boards are checked for their quality and only two outcomes are expected: either the circuit boards are defective (have some defects/don’t work properly/do not pass the quality tests) or they pass the quality checks and are packaged to be shipped or placed in ready to use inventory.
  • ECBs are important for any electrical equipment.
  • Their quality statistics can make or break equipment and which in turn causes disruption in manufacturing, supply chain, logistics.
  • The defective units are recorded, their output rate is monitored, and based on these analysis is done to check the quality of the ECBs.
  • This analysis is done through the Statistical Process Control using the various quality tools and techniques for the enhancement of the quality control in the manufacturing.
