Abstract
 This dissertation mainly introduces one kind of new equipment which is suitable to electronic products to carry on the high temperature aging experiment. Through the change of the high temperature as well as the electric power such combined .Exposing circuit wafer''s flaw, like the bad welding, unmatchable of the primary device parameter, floats warm as well as in the process of manufacture breakdown, with the aim of giving to reject, and also have function of  stabling the parameter for  the non-flaw''s circuit wafer. Thus it gives the safeguard to the enterprise product quality. SCKey is a control configuration software platform which completely supports the all types of programmers in this system.  through simple pull-down menus and pop-up dialog, SCKey configuration software establish a friendly man-machine interfaces and a large number of Windows control standards, so that the operation  maintained consistent, and more easy to learn and use.
  This dissertation is mainly to finish the aging process automation design, site layout design of hardware, software configuration through the PLC, the communication between the computer research. Through this design, getting a better understanding and in-depth study of the mechanical and electrical integration of products related to the development of design. Through the further control system design, to achieve real sense of the combination of the machinery and electronic products .The article lists the research background of this equipment, the systems control principle, the major technique parameter and the electrical principle, which has been made all detailed elaboration, and have a discussion for the test results
 
Key words:  High temperature aging ; Closed-loop control ; Configuration control ; PLC ;  Data transmission .
