Wafer loading and unloading equipment and wafer aging test system

ActiveCN224538688UReduce the number of viasavoid blushing
The application relates to the technical field of wafer testing, in particular to a wafer feeding and discharging device and a wafer aging test system; the wafer feeding and discharging device comprises a heat sink carrying assembly, a heat sink carrying slide rail and a heat sink loading platform for carrying a heat sink, the heat sink loading platform is in sliding connection with the heat sink carrying slide rail, one end of the heat sink carrying slide rail is a wafer loading end for wafer feeding, the other end of the heat sink carrying slide rail is a loading feeding end for conveying the wafer after wafer feeding to a next process and for recycling the empty heat sink; the wafer material taking assembly comprises a wafer material taking slide rail and a wafer adsorption device for adsorbing a wafer, the wafer adsorption device is in sliding connection with the wafer material taking slide rail, and the wafer adsorption device is arranged above the heat sink carrying assembly; the wafer adsorption device is arranged in the wafer feeding and discharging device, and the wafer is placed on the heat sink from top to bottom, so that the number of through holes on the surface of the heat sink is reduced, and then the back of the wafer is prevented from whitening.

Signal lamp halo processing method and device and electronic equipment

PendingCN121865116AAvoid halo situationsreduce complexityOriginal dataSignal light
The invention discloses a signal lamp halo processing method, a signal lamp halo processing device and electronic equipment. The signal lamp halo processing method comprises the following steps: acquiring a bright frame and a dark frame for capturing the same Bayer; performing gamma mapping on the highlight area in the dark frame to obtain a fusion mask of the bright frame and the dark frame; performing brightness and saturation suppression on the original RGB data of the dark frame based on the pixel values of the original RGB data of the dark frame in different color channels to obtain first RGB data after dark frame suppression; converting the first RGB data into first YUV data after dark frame optimization; fusing the first YUV data with the original YUV data of the bright frame based on the current height and the fusion mask in combination with the pixel-level gradient weight and the height gradient light intensity gain of the current pixel to obtain second YUV data of a first fusion image of the bright frame and the dark frame; converting the first RGB data into second RGB data of the first fused image; and in combination with a preset halo removal level, performing halo removal processing on a halo region in the second RGB data of the first fused image.
