Bare and Assembled PCB Inspection through Graphical User Interface

Abstract: The nature of the defects present in the Bare and Assembled PCBs are entirely different and also the algorithms used for the inspection of these two boards are not common. However, the inspection of both Bare and Assembled PCB has some commonality such as image pre-processing, etc. The main objective of this paper is to develop a common Graphical User Interface so both of these algorithms can reside in the same computer resource and can decide based on the type (bare or Assembled) to identify the defects.

Keywords: Printed Circuit Board, Bare PCB Defect, Component and Solder joint defects, Graphical User Interface.
