Abstract: A capacitive touch screen, having a first transparent substrate provided with a touch circuit layer. The touch circuit layer is provided with first and second electrodes and a jumper portion. The touch screen is further provided with an insulating layer. The insulating layer is continuously disposed in an entire transparent touch area of the touch screen, and is provided with through holes at the jumper portion to form a jumper connection of the second electrode. The touch screen further includes a shielding layer sandwiched between the first transparent substrate and the touch circuit layer, and contains multiple shielding blocks. The shielding blocks correspond to the through holes, and the contours of the shielding blocks are formed by expanding the contours of the through holes outwards. The capacitive touch screen can effectively reduce side light reflection on an edge slope of the insulating layer, thereby avoiding interference with display.

Abstract: The present invention provides a polishing roll capable of, for example, realizing three-dimensional polishing of hard materials such as sapphire glass at a high removal amount. The polishing roll is a cylindrical polishing roll capable of rotating about a central axis, characterized in that the polishing roll includes a core part serving as a central axis to which torque is applied, an intermediate part having a cross-section concentric with the core part, and a polishing part disposed on the outer peripheral surface of the intermediate part, and the intermediate part is made of a cushion material that is softer than the polishing part.

Abstract: A semiconductor product includes a die and leadframe included in a package made of plastic or other insulating material. The die and leadframe are dimensioned so that they overlap in at least one location. One or more pillar bumps, formed from as a cylindrical conductive base topped with a solder bump are used to interconnect the leadframe and die in the region of overlap. The pillar bumps perform several purposes including: electrical connection between the leadframe and die, support for the die during packaging and conduction of heat away from the die.
