20150042980 | DEVICE FOR DETECTING QUALITY LEVEL OF MICROELECTRONIC PACKAGING SAMPLES USING PHOTO-THERMAL IMAGING - An image acquisition device based on photo-thermal imaging, including a support beam, a translational electric motor, an imaging probe, and a light emitter. The translational electric motor is fixed to the lower side of the beam, and the imaging probe is perpendicularly fixed to a moving block in the translational electric motor. The light emitter is connected to the moving block via an adjustable connection piece, and by adjusting the adjustable connection piece, light emitted by the light emitter enters the imaging probe after being reflected by a sample. The moving block in the translational electric motor is configured to move the light emitter and the imaging probe in the radial direction right above the sample. The light emitter is configured to emit light on the upper surface of the sample. The imaging probe is configured to image reflected light from the upper surface of the sample. | 02-12-2015 |

20100185893 | Topology Collection Method and Dual Control Board Device For A Stacking System - The invention provides a topology collection method and dual control board device applicable to a stacking system comprising dual control board devices. A master control board of a dual control board device advertises through a stack port the topology information of the member device in which the master control board resides, including information about the master control board and, if a slave control board is present, information about the slave control board; and stores the topology information or updates the existing topology information upon receiving the topology information of the stacking system through the stack port, and backs up the stored topology information of the stacking system to the slave control board after the slave control board is inserted. This invention is applicable for collecting the topology information of a stacking system comprising distributed dual control board devices. | 07-22-2010 |
