Abstract: The purpose of this research is to reduce the machine breakdown time by applying the proper preventive maintenance program to increase the Mean Time between Failure (MTBF). The focus of this research is to study and analyses the causes of those effects on the failure of HGA tester hang by using Logistic Regression Analysis. The purpose is to find the relationship between the cause of the breakdown and failure. As a result from the analysis it is found that causes occurred from Pogo 6 pins, Mounting Block, Shoe, Media, Head amp, and X, Y have a significant relationship with the failure at the HGA tester. The failure period is analyzed in order to set the preventive maintenance program and to increase production capacity by reducing the percentages of downtime of the machines. After applying the preventive maintenance program to the case study factory, the Mean Time between Failure (MTBF) can be increased from 75.05% to 87.92%. Moreover, frequency of failure average is reduced by 42.87% and the number of breakdown times on average can be reduced from 130.34% to 56.69%.
