    Abstract: A transmission line conversion apparatus connecting a parallel transmission line to a coplanar waveguide (CPW) is provided. To this end, the CPW including a transmission line composed of a signal line and a ground line which is formed on one surface of a dielectric substrate, and a parallel transmission line connected to the CPW, at a predetermined angle with respect to a substrate constituting the CPW, and composed of a signal line and a ground line, are proposed. In addition, the signal line of the CPW and the signal line of the parallel transmission line are connected to each other, and the ground line of the CPW and the ground line of the parallel transmission line are connected to each other.

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.
