    Currently, the HDDs (Hard Disk Drives) from a production line have to pass an operation test in a burn-in chamber. To ensure quality, after an operation period, the burn-in chamber has to be calibrated. The calibration process requires an engineer to manually monitor a temperature at the hybrid temperature recorder connected to the burn-in chamber throughout the entire process. It is a time consuming operation and inefficient process due to a large number of burn-in chambers used in the production line, when comparing with a limited number of engineers. This paper expresses a development of hybrid temperature recorder monitoring system used to improve such the calibration process. There are two main systems involved, i.e., a temperature recording system and a monitoring system. However, the monitoring system is mainly focused in this paper. Also, an object-oriented analysis and design methodology (OOADM) is applied in the development process. The monitoring system interconnects the hybrid temperature recorder through a wireless network to receive the temperatures captured from sensors inside the burn-in chamber. Then, the temperature data is processed and displayed at the central server of system in the engineering office. This could allow the engineer to centrally monitor all hybrid temperature recorders used in the calibration process of burn-in chamber in real-time. The monitoring system can display the alarm signal when the errors occur during the calibration process and sent it to the engineer for alerting as well. Furthermore, the temperature data can be stored in a database at the central server for future reference. ©ICROS.

    Currently, the calibration of burn-in chambers used in a HDDs (Hard Disk Drives) production line requires an engineer to manually monitor temperatures at the hybrid temperature recorders throughout the entire period of calibration process. It is a time consuming and inefficient operation, due to a large number of burn-in chambers used in the production line comparing with a limited number of engineers to handle. Therefore, this paper describes the prototype development of hybrid temperature recorder monitoring system implemented to improve the current manual calibration process of burn-in chamber. The work in this paper applies an objectoriented analysis and design methodology (OOADM) in the development process. The proposed system comprises two subsystems, i.e., a temperature recording subsystem and a monitoring subsystem, interconnected through a wireless network. The temperature recording subsystem performs capturing temperatures from sensors inside the burn-in chamber and sending the temperature data to a central server at the monitoring subsystem in the engineering office for monitoring in real-time. When the errors occur during the calibration process, the alarm signal is displayed and sent to the engineer for alerting. Furthermore, the temperature data is stored in a database for future verification and reference. © 2010 IEEE.
