Abstract

Nowadays, electronics manufacturing industries are rapidly developing. Most of electronics used copper based board to mount small electronic components. Due to continuous current flow, copper board temperature increases. Heat transfer devices need to be mounted on that board to sink the excess heat from the board to improve the performance. This study is focusing on the corrosion prevention of heat sink terminal surface by using antirust coatings. Heat sink terminal which generally made of steel easily get corroded when exposed to environment. In this project, heat sink sample is made of Eco-Trio steel (or known as ZSNC steel), one of the Nippon Steel product. Heat sink manufacturer basically used steel terminal to reduce cost compare to other materials. However, using steel as terminal creates other problem to manufacturer which is corrosion or commonly called rust. This rusty terminal will resist any solder liquid, which means, heat sink terminal will not perfectly banded together to the copper board. Rust is critical problem in electronic manufacturing industries because it has potential to stop production line for substantial duration if no action taken to prevent this problem. The literature review has been divided into three parts which are study on corrosion, heat sink and antirust coatings. Several organic coatings have been selected for the study. The scope of study also includes the data weathering experiment which is important in simulating the similar condition for ageing process of coated samples. Besides, a few ISO Standards has been studied to guide the coating experiment to ensure the reliability of experiment conducted. Six methods has been suggested for this project include the research part, information gathering from journals and books, test procedure preparation and samples purchasing, coating process, manual and solder dip process and optimum antirust coating selection. Finally, this project should be a useful addition in order to understand the corrosion on heat sink terminal and its prevention by using antirust coatings. Hence, the outcome of this project should give benefits for all of the parties involved; particularly the student himself.
