PURPOSE:To properly connect according to IC usages by providing a socket for connecting IC and through holes which are electrically connected with each end of the socket one by one. CONSTITUTION:A printed board 1 is provided with through holes 2, and a socket 3 is also mounted on the board 1. Holes and terminals of the socket 3 are electrically connected with each other respectively. Whean IC is tested, the IC is inserted into the socket. So, the IC can be easily mounted or dismounted at any time. Upon completion of the IC test, the IC is directly soldered to the through holes. Therefore, no imperfect contact will occur due to vibration. |
