This paper presents a methodology for optimization of line scan path on fixed panel displays (FPD) using a modified self organizing map (SOM). The existing scanning method of defective thin film transistor (TFT) lines on FPDs by a non-contact moving sensor is top down and unidirectional which is time consuming. First, the problem is approximated to a well(More)
—In inspections of printed circuit boards (PCBs), a test probe has to be moved to a number of PCB wiring patterns in some order. This paper considers path optimization for minimizing a total path length of testing PCBs arrayed on a plane. Due to the miniaturization of PCBs, the procedure of " alignment " has been recently needed in order to know the exact(More)
