The Research Of PCB Thermal Design Based On Icepak

Analyzing Instrument is an important part of instruments. It can identify and measure materialconstituents. The Analyzing Instrument has three main kinds of production: spectroscopy,chromatography, and mass spectroscopy. With the development of New High-technology, such asmicroelectronics, micromachining, Information Technique, new material, computer science,Analyzing instrument tends to develop to modularization, miniaturization, intelligent. These forcethat the volume of chip becomes smaller and smaller, the density of the Printed Circuit Boardbecomes more and more intensive, the working frequency of system becomes faster and faster. Sothe problem faced by Analyzing Instrument same as electronic equipment is thermal Problems.Analyze Instrument is divided into types, such as on-line, portable type and laboratory...etc., havinga dissimilarity with the traditional single board thermal design device, the on-line and the portabletype instrument usually have the request of the antiknocking and the IP protecting, and theincapability depend the blow fan, cold board etc. Thereupon aim at thermal design characteristics ofanalyze instrument, the single knothole thermal design device in the requirement speciality analyseinstrument.The author passes the annum multi-study and practices, applying Icepak software to imitate,designs from the PCB of wire, copper and via etc. the factor, combine thermal simulation tool, steerto the heat transfer by radiation agent in the PCB design in detail thermal analysis, on this ground,in order to improve the efficiency of the PCB design, reduce the thermal objection during thedesign,improve the heat transfer by radiation capacity and reliability of the PCB, put forward thedesign rules which should notice and abide during the PCB design. Secondly, the text aims at thehot characteristic performance of same circuit on different board material, drive board as bearer bythe analyse apparatus rate of work, make use of the hot characteristic that the thermal simulationtechnique available to display a different board material; Verified with the actual casus ultimatelyhow thermal simulation analyse to manage pure thermal design way of thinking through a caloricunder the closeness system, reach the target of the design, real imitated the thermal design criterionand caloric really to apply to the actual casus analyse item scheme amid. Study the thermal designof the fruit to instruct analytical apparatus be a particularly on-line analyse apparatus, lifting theproduct mass thus, have weighty sensus.
