In order to improve a damage of connection part of Main Board Memory, we developed a hazard extension card(Socket Jig). The damage occurs during the test of the memory module product of the Desktop-PC. The connection part of main board was broken by 15％ per a day before the development. There existed two major problems; One was that we must obtain more than 15％ of surplus equipment. while the other was that we needed people who were wholly responsible for repair. The development of extension card decreased operation delay. Besides, it improved capacity of surplus equipment and operation efficiency. Therefore, we can save 78,000,000 won per year.
