Abstract
Western Digital (WD) uses pallet system for holding solid state drive’s (SSD) printed circuit boards (PCBs) in their assembly line for automated assembly process. The existing pallet system used by WD is fixed in size, requiring the creation of new pallet designs whenever PCB sizes change, leading to increased costs and production downtime. This thesis addresses the need for an auto-size system to accommodate different sizes of PCBs in the assembly process of SSDs. The objective of this project is to develop an electromechanical system using linear actuators to set the handles on the pallet to the correct coordinates for holding various PCB sizes. The project involved investigating possible substitutions for the PCB assembly pallet, designing, and fabricating the system components, and developing a control system for accurate positioning. Experimental testing demonstrated the system's precision and accuracy in accommodating PCB sizes within the specified range. Additionally, suggestions for future improvements, such as integrating machine learning for PCB size determination and using more robust materials for enhanced precision and longevity, were discussed. The successful development of the auto-size system offers significant potential for optimizing production processes, reducing costs, and increasing productivity in the
manufacturing of SSDs.
