The main purpose of failure analysis is used to assist the designers and manufacturers to analyze the factors of failure of an element and explore the solutions in order to improve the quality of the products and rise the compete ability of the industry. Therefore, how effectively to execute the failure analysis and constructing the related procedures are the main goals of this study. The present works were concentrated on the failure analysis method of the electronic devices and the construction of the failure model. The major work includes the procedure of failure analysis, experimental tools, and the solutions of related problems. In this study, we should first make understandings of the equipments and related information. Among enormous real elements, five cases were chosen to study the procedure and method for failure analysis. For constructing a suitable and useful database, the required equipments to probe the causes of failure must properly be selected. The construction of failure model is a hard work since it can affect the failure event to be occurred again or not. In this study, the data based on 1021 modules were analyzed statistically; the failure model was introduced induced in the test items of environmental testing and category of failure causes were investigated.
