Semi-conductor package is a very complicated process. In the early years, the process is a combination of manual labor and semi-automation. As the automation technology is promoted, the size of the semi-conductor is smaller, and the demand for high density die bonding is getting higher, semi-conductor manufacturing has gradually become fully automatic. Because the range of the manufacturing process is very wide, this thesis only focuses in the die bonding process, especially for the TO220 package process. TO220 package is very suitable for the high power devices in the automobile and computer industries. In order to study deeply in this process, this research cooperated with a professional semiconductor equipment manufacturer. The purpose is to develop useful equipments for the industry. The method of this research includes several steps. First, we have studied the TO220 package process, and proposed a functional description of the equipment. We discussed with company to verify the proposal, and then began to divide the equipment by different modules. Each module was designed and carefully verified by the whole research team. Finally, the equipment is accomplished. To verify the performance of this system, we have used a high speed camera to detect the motion of the mechanisms. The results were used to modify the design. To understand the quality of the die bonding, a 2.5D image measurement equipment is applied to measure the offset of the chip and the lead frame. The data is analyzed by a histogram to check the accuracy of the die bonding process. There are two main results of this research. First, we have built a prototype of the die-bonder. The prototype includes a work holder module, a wafer table module, an image inspection system, and the spanker/dispenser mechanisms. Because the pick and place device is the core of the system, the research has devoted to develop a crank-rocker mechanism. The mechanism is very simple, and requires only one servo motor and a z-axis VCM to perform the arc pick and place motion. The accomplished pick and place machine is low-cost. The maximum speed can reach to 11000 UPH, and the accuracy and the repeatability are kept within 0.05 mm.
