Because the solder fillets of BGA jointsare formed beneath the BGA ball, it is necessary to acquire the cross-sectionalimage using X-ray digital tomosynthesis (DTS) method. In the existing DTS systems,the images are acquired by the outer domain of image intensifier to reconstructthe cross-sectional image. But, the acquired DTS images are distorted and blurreddepending on the surface shape of image intensifier. In this paper we present a new DTS system called the ODSR (object-detector synchronous rotation) system.Using the ODSR system, we compensate the problem caused by the shape distortionand the intensity attenuation with the BGA sample images. We also realize the cross-sectional images on the arbitrary focal planes of BGA fillets by geometricalreconstruction to evaluate the soldering states of BGA.

For Automotive Body Control System(lamps, power window, mirror, seat positioning and etc.), a control method using that is proper at low cost.[1] If we use CAN in vehicle, we can share information in each device, control with digital data and have flexibility to make design changed without physical changes to the main wiring harness.
This paper discusses fault detection and diagnosis of each CAN node when faults happen in Automotive Body Control System. In this paper, Body Control System involves DC motor control, lamp on or off control, and other low data traffic application. The proposed diagnostic software and protocol will enhance the diagnostic ability of vehicle.

In a digital controller of brushless DC Motor, the control accuracy is of a high level, and it has a fast response time. We used a hall IC signal for the permanent magnet rotor position and for the speed feedback signals, and also for a micro controller of 8-bit type (80CL580); furthermore, we designed the fuzzy logic controller and implemented the speed control system of brushless DC Motor. To acquire an accurate fuzzy logic control algorithm, a simulation with the MATLAB program has been made, while the performance of the system, done with an experiment for a unit step response, was also verified.
