Electrical Properties In The Dvd Structure Design

Because of the special performance, price and abundant software support,DVD became a new force suddenly rises and a new hotspot of domestic electricconsumptive in the market. DVD is the first integrative product in digital AV domain.The main way that can eliminate or reduce the disturb of electromagnet in thedesign of EMC (Electro Magnetic Compatibility) is shield .For example, we addground patch on the MIC PCB board and ground cable on the Front PCB board toreduce the disturb of conduction. And we cut off magnetism gateway by fixingbracket on the big transformer. In thermal design, we solve the problem of scatterthermal by set up radiator on the transistor and add airways on the surface.This paper is on the basis of theory and practice, it analyze the problem duringthe design from the point of the structure design. At last, we solve problems byshield and radiator , and make our product get high quality and satisfy the custom'sdemand. By the basic theory, count method and the process of heat transport andexperiment, analysis, research,This paper has five chapters, it intro the DVD's structure design by the aspectof the EMC, thermal and integer. Through this design, we know we must performtechnical scheme to enforce product's capability, reliability, only this the product canattain the anticipative result...
