Aiming at producing highly uniform ultra-small solder bumps to meet the growing requirements in the area array package, a novel fabrication method based on piezoelectric diaphragm-piston droplet jetting was proposed. The principle and customized equipment of this method were introduced. Solder bumps with a diameter less than 100 mm were successfully fabricated with the customized equipment. The main...

Integer-forcing (IF) linear receiver has been recently introduced for multiple-input multiple-output (MIMO) fading channels. The integer coefficients have to be chosen based on the channel realizations, and the choice of such coefficients is known to determine the receiver performance. It has been proved that Integer-forcing receiver outperforms the minimum mean square estimator (MMSE) and zero-forcing...
This paper introduces a kind of method based on chaos and fast curvelet transform. At first, the watermark is done the scrambling by the Arnold transform. Then the digital wartermarking is done the chaos encryption by the chebyshev chaos sequences. At last, the watermarking image that has been done the chaos processing is embedded into the intermediate frequency coefficient of image that has been...
