Abstract
In a testing board ( C), one end of each of a plurality of first wirings ( ) and one end of each of a plurality of second wirings ( ) are connected to a common point ( ). The other end of each of the second wirings ( ) is connected to a terminal ( ) of a semiconductor device ( ) under test. The second wirings ( ) have almost the same length. Signals outputted from drivers of a tester pin ( ) to the first wirings ( ) are composed at the common point ( ), and the composite wave is inputted to the terminal ( ) through each of the second wirings ( ). A relay ( ) is provided at a midpoint of each of the second wirings ( ) and is controlled such that the signals can be inputted to, for example, the terminal ( ) from the driver of the tester pin ( ) through one of third wirings ( ).
