Metal Package Rectifier Diode Design And Manufacturing

This paper was studied about the designing and manufacturing process of the metal-packed rectifier diodes. That was a extremely complicted process which included dozens of procedures , such as oxidation diffusion, photolithography and evaporation . Especially now, Most of the semiconductor enterprises decide to change its production mode which from selling the old stock to take orders from the clients. And this new mode increases the complexity of the production process which I mentioned before . Such devices has the characteristics of high efficiency of rectifier in the specific application . It will be widely applied in many fields of the manufacturing all kinds of electrical appliances , electronic instruments circuit and protection circuit . This new process also has a broad prospect of application in making military machines besides the civil supporting . The metal-packed rectifier diode is normally a high-power cavity device which asked for the importance of reliability . Rational structure designing and thermal designing are the key to success of manufacturing the metal-packed rectifier diode. However , the Craft welding, the corrosion and the sealing cap control technology are the difficult part in process. This paper is based on the above problems and the innovative and the exploring research has been made. Main content as follows :1. Studying the impact of the the main manufacturing process of the performance of the product. Designing and manufacturing process of the metal-packed rectifier diodes was a extremely complicted process which included dozens of procedures , which will deside or even affect the quality of the products in some in some way.2. Focusing the influence from the process of the manufacturing environment.3.Studying the problem which will appear in testing link.4. As 2CZXX of manufacturing process, I detailed the description of the metal- packed diode production process .
