<p><P>PROBLEM TO BE SOLVED: To provide a damage index prediction system of electronic equipment which enables high-precision damage prediction of mounted components and the like on a circuit board. <P>SOLUTION: The damage prediction system predicts the index about the damage of a joint of the electronic equipment having a joint which electrically connects electronic components to the circuit board for mounting and a joint for detection which is designed so that its lifetime is lower than that of the joint. The damage prediction system includes a database in which the relationship about the index of the breakage of the joint and the index of the breakage of the joint for detection is accumulated, a breakage detector which detects the breakage of the joint for detection, and a calculator which calculates the predicted value of the index about the damage of the joint from information about the breakage of the joint for detection obtained by the breakage detector and the relationship accumulated in the database. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
