In general, when an IC chip is inserted to configure an electronic circuit, the socket is soldered and fixed in advance on the circuit board, and the IC chip is inserted into the socket for use. Therefore, the experiment is performed while changing the configuration of the electronic circuit. If necessary, soldering electronic devices directly to the board constitutes an electronic circuit, and it is not only cumbersome to remove the solder attached to the electronic device again and to separate the electronic device from the board, but the electronic device may be exposed to a lot of heat.
