Although the mobile head-mounted gaze tracker (HMGT) has gained its great success in human-machine interactions, the real implementation of HMGT still poses several significant challenges. The parallax error and the tedious calibration procedure, as two of these challenges, will be addressed in our proposed two-step calibration method. In the first step, instead of fixating at several pre-defined...
The well-controlled droplets jetting forming permits high efficiency in bonding wire manufacture. In order to achieve better control of the droplets jetting forming, numerous parameters in the jetting process should be studied. This article study the effect of substrate temperature on the solidification of tin bonding wire. Experiments on the solidification of tin bonding wire under different substrate...
As a uniform solder balls manufacturing technology, metal droplets jetting technology can realize controllable deposition of droplets, so it can apply to the production of solder balls array in BGA and CSP packaging. To study the influence parameters to the morphology of the solder balls, we developed an equipment based on the Pneumatic diaphragm drop-on-demand Technology. In this paper, we changed...
