Abstract
A grid clustering-based system for locating abnormal area of solder paste printing and a method thereof are disclosed. In the system, an analysis device divides circuit board size information to generate divided grids based on grid size information, when a total number of at least one bad solder joint of one of the divided grids is determined to be higher than or equal to a density threshold value, the analysis device sets the one of divided grids as a high dense grid, the analysis device then integrates the divided grids, which are high dense grids and interconnected to each other, as a high-dense bad solder joint area. Therefore, the technical effect of integrating high dense areas of bad solder joint to locate the bad solder joint can be achieved.
