    • A semiconductor package circuit board has an indicator for specifying a location of a defective circuit board unit. The semiconductor package circuit board includes circuit board units arranged in an m-by-n matrix pattern. The indicator has marking areas arranged in an m-by-n matrix pattern so that the marking areas are marked in correspondence to locations of identified defective circuit board units of the circuit board units. An operator can readily put a defective mark on the indicator without any confusion. The operator or a sensor can readily recognize the defective mark. Since the indicator can be formed on the circuit board unit, the integration of the semiconductor package circuit board can be increased, and the productivity can be substantially improved. Furthermore, a pathway of the sensor can be reduced, and interferences that might occur if the sensor moves can be hindered.
    • 半导体封装电路板具有用于指定有缺陷的电路板单元的位置的指示器。 半导体封装电路板包括以逐个矩阵图案排列的电路板单元。 指示器具有以逐一矩阵图案排列的标记区域,使得标记区域对应于电路板单元的识别的有缺陷的电路板单元的位置被标记。 操作员可以很容易地在指示器上放置有缺陷的标记,而不会有任何混淆。 操作员或传感器可以容易地识别缺陷标记。 由于可以在电路板单元上形成指示器,因此可以提高半导体封装电路板的集成度,并且可以显着提高生产率。 此外,可以减小传感器的路径,并且如果传感器移动可能会发生干扰。
