The precise positioner is composed of monolithic parallel flexure mechanism, horizontal and vertical electromagnetic actuators, and optical displacement sensors to achieve the 6-DOF motion. The concept of the system intends to achieve three goals: 1) large travel range, 2) high precision positioning, and 3) fast response. In our system, there are eight sets of permanent magnets attached to the moving platform, and eight sets of electromagnets mounted on the bottom platen. The whole control architecture is to take the six posture data measured by the six optical displacement sensors first and then to control the 6-DOF motion by regulating the current in the electromagnetic actuators. For the purpose of system robustness and stability, an adaptive sliding-mode controller is proposed to validate the system performance. The developed robust adaptive control architecture consists of two components: 1) sliding mode controller, 2) adaptive law. From the simulation and experimental results, satisfactory performances of the hereby developed system, including stiffness and precision, have been successfully demonstrated.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115538635","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}

Solder bump is used as an electrical junction of these packages, and they cannot be observed from outside. X- ray fluoroscopy is used as inspection method. It cannot evaluate the shape of solder bump correctly because information is compressed along the ray. The oblique CT is considered as a method for accurately examining the shape of the solder bump. Conventional oblique CT still has the speed and mechanical constraint, and it cannot be introduced into the soldering line. In this paper, we propose the novel oblique CT system that can non- destructively obtain the 3D shape of solder bump at a high-speed. This system obtains the projection images from various directions using the rotational transfer of flat panel detector and the fixed mounted open-type X-ray generator that has a wide radiation angle, and reconstructs 3D image using the 3D FBP (Filtered Back Projection) method. In addition, we have developed the reconstruction acceleration unit for oblique CT, and thus the 3D image is obtained in the real time. In our experiments, we evaluated the solder joints of BGA mounted substrate. The result demonstrated that the proposed system obtained the information that was able to determine the good or defective situation in soldering. This system is the world's first CT system, which can be introduced into the soldering line, and it is operated by more than 20 domestic and foreign factories now.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121315305","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}

The method has the same effectiveness as that of Smith predictor and the validity has been experimentally verified. Furthermore, the advantage of the method is that it works without delay time model. However, whereas the method has been practically applied in several situations, the robustness has never been studied so far. In this paper, we present robustness of the time delayed control systems with the time delay compensation method. Some problems caused by model uncertainty and constraint on cutoff frequency are firstly discussed. Then a time delayed control system with communication disturbance observer based on two- degree-of-freedom control structure is designed. The control system makes it possible to achieve zero steady-state error. Moreover, the transient response is designed easily by parameters of controllers. Here, the transient characteristic and the attenuation performance of model uncertainty can be designed separately. Simulation results verify the validity of the control system.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121711427","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}
