However, during normal operation, the same thermal resistance limits the heat transfer for power component dissipation. The narrower the thermal pad, the greater temperature increasing during power dissipation. Hence, the dimensions of the thermal pads are critical. The work presents the results of a practical approach not for a hole via or a pad for an ordinarily component connected to a large copper area, but a medium power Surface Mounting Device, SMD, using the Printed Circuit Board, PCB, as heat sink. There are taken into consideration different thermal pads and there are investigated by temperature measurements with thermocouples and thermovision. The variables are the thermal pad dimensions, the area of the radiant surface, the base material of PCB, and the reflow soldering process. It is analyzed the effect of the thermal pad versus the temperature on the soldering pad and beyond the thermal pad and on the case of the device during reflow soldering process and during operation","PeriodicalId":155180,"journal":{"name":"2010 IEEE 16th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126764578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For modeling of power transformers, we implemented a Matlab software, based on mathematical equations who describe the functionality of power transformers. Also we compare the Matlab results with a Pspice simulations results. Matlab program that we've implemented enables the modification of input parameters of the transformer and the choice of a circuit to be analyzed.

Schematic design and thermal management are rarely correlated, although electrical and thermal parameters are very closely linked. Poor thermal design can have severe consequences on the reliability and functionality of the equipment and is often the main cause of component failure. As power density increases on the printed circuit board this problem becomes critical. Our paper presents a method of mixing electrical and thermal simulation with the goal of improving functional parameters and thermal stress behavior. Switching-mode power supply circuits have high power density and are likely to fail due to thermal stress, so as a support application for our method we will use a boost switching-mode power supply designed for automotive use.","PeriodicalId":155180,"journal":{"name":"2010 IEEE 16th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116946925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the basis of student's knowledge is learned during faculty year's classes, it has been widely shown that the easiest way of developing practical skills is done during practice stages either in universities or in private companies [1]. During one such stage the student improves his or hers skills in areas such as researching, computer simulation, interface developing, and of course, maybe most important, packaging. The practice stages offer the student the possibility of implementing circuits and projects, either by realizing testing boards or by using breadboards [2]. These are skills that are rarely attained during faculty classes due to the fact that there is not enough time for each student to implement projects during laboratories. This is why practice stages are the ones that truly give the student a basis in electronic packaging.","PeriodicalId":155180,"journal":{"name":"2010 IEEE 16th International Symposium for Design and Technology in Electronic Packaging (SIITME)","volume":"304 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122723805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
