Design and development of a conveyor system for semiconductor industry

Abstract

Conveyor system is an essential part in a Semiconductor Industry. It is used to transfer leadframes from one work station to another. As leadframe is a very delicate item and care must be taken not to damage them as any scratch marks or dents found on it will lead to it being scraped. Therefore, the design of the conveyor system is important. A good conveyor system will help to save up in the production process, time and most importantly cost. Nowadays, companies with high end products have suddenly swamp into Singapore. This is due to it's attractive location, extensive telecommunications connectivity, superior logistics and supply chain infrastructure. Companies like Matsushita Electric and Chartered Semiconductor has invested hundreds of million dollar into it. These show that the semiconductor market is in the midst of a strong growth in equipment and materials, and all indications are that this trend will continue for a long time. Therefore a good process line is required for the manufacturing of the products in order to keep pace with the ever increasing demand. This is when a good conveyor system comes in handy. The main objectives of this research project are to: - Design and develop a custom made conveyor system to help in transferring the leadframe from the press machine to the stacker, whereby the leadframe will be nicely stack up after being cut, without damage. - Separate the four strands of leadframes that is been cut out from a coil by the press machine, to aid in the stacking process. - Save production process, time and cost.
