BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insertion / removal tool for inserting / removing an IC device from / to a burn-in socket used for burn-in / test of an IC device.

[0002]

2. Description of the Related Art In order to evaluate the reliability of a semiconductor integrated circuit (IC), a so-called burn-in test for testing a circuit operation is generally performed in a high-temperature (and high-humidity) burn-in furnace. At this time, the IC device is equipped with a number of sockets (burn-in boards) mounted on a test board called a burn-in board on which a predetermined circuit is formed.
Socket).

In particular, there is a socket for mounting an IC device carrier in which an IC device is mounted in a carrier (carrier) as shown in a perspective view in FIG. The socket body is formed of a heat-resistant material such as polyethersulfone except for some metal members.

In the drawing, reference numerals 41, 41 denote device locking members, respectively, which are provided with a pair of wall plates at opposing positions, and are opened rightward and leftward outward from a vertical position with a pin 42 as a fulcrum to be inserted into the socket. In order to receive the carrier and fix it, the opening / closing operation of returning to the original position is performed by the restoring force of the spring 43 supported by the pin 42. 44 is I
This is the connection (contact piece) between the terminal of the C device and the circuit of the burn-in board. Conventionally, as a method of mounting an IC device carrier in a socket, there are a method of manually operating the device with a fingertip and a method of using an automated machine.
