    • The present invention relates to a method for generating a compensation matrix in a process of circuit board inspection. The method comprises: a step of selecting an arbitrarily predetermined number, N1 (N1>=2), of feature object information within a FOV of substrate; a step of generating a first compensation matrix based on the feature object information extracted from the substrate; a step of comparing an offset value of each of all the feature objects with the predetermined reference value by applying all the feature objects within the FOV to the compensation matrix, and counting the number of feature objects of which offset value of the each feature object within the feature objects is no greater than the predetermined reference value; and a step of repetitively performing the above mentioned steps N2 (N2>=1) times, and generating a second compensation matrix using information of feature objects that have an offset value which is no greater than the predetermined reference value, in case the number of the counted feature objects is the maximum.
    • 本发明涉及在电路板检查过程中产生补偿矩阵的方法。 该方法包括:在基板的FOV内选择特征对象信息的任意预定数量N1(N1> = 2)的步骤; 基于从所述基板提取的特征对象信息生成第一补偿矩阵的步骤; 通过将FOV内的所有特征对象应用于补偿矩阵,将所有特征对象中的每一个的偏移值与预定的参考值进行比较,并对其中每个特征对象的偏移值进行计数的步骤; 特征对象不大于预定的参考值; 以及重复执行上述步骤N2(N2> = 1)次的步骤,并且使用具有不大于预定参考值的偏移值的特征对象的信息来生成第二补偿矩阵, 计数的要素对象是最大值。
