Semiconductor component test device and method of testing semiconductor components

A semiconductor-component test device for testing a semiconductor component having a first terminal and a second terminal, the semiconductor-component test device comprising:

• a power supply having a third terminal and a fourth terminal, and being for supplying either a test current or a test voltage;
• a first connection member;
• a second connection member;
• a switch circuit board on which a switch circuit is either mounted or formed;
• a first connector attached to the switch circuit board;
• a first conductor plate or conductor bar, attached to the switch circuit board;
• a second conductor plate or conductor bar, attached to the switch circuit board;
• and
• a mother board;
• wherein
• the third terminal, and the first conductor plate or conductor bar are electrically connected;
• the second conductor plate or conductor bar, and the first connection member are electrically connected;
• the first connection member and the first terminal are electrically connected;
• the second connection member and the second terminal are electrically connected;
• the second connection member and the fourth terminal are electrically connected;
• the switch circuit board is connected, via the first connector, with the mother board;
• and
• the switch circuit carries out a first operation that electrically short-circuits the first conductor plate or conductor bar and the second conductor plate or conductor bar, and a second operation that electrically opens the circuit between the first conductor plate or conductor bar and the second conductor plate or conductor bar.
