The reliability evaluation and analysis for general electronic components are required to guarantee in quality and in efficiency. Reliability prediction of the interface card, which is used in the CNC controller of machine tools, was carried out using MIL-HDBK-217F and PRISM database. Reliability performances such as MTBF(Mean Time Between Failure), failure rate and reliability were obtained, and the variation of failure rate for electronic components according to temperature change was predicted. The results obtained from this study are useful information to consider a counter plan for the weak components before they are used.
