Abstract: A method for dicing a sheet workpiece includes the following steps. A base (10) is provided. A water-soluble adhesive (20) is coated onto the base, and the workpiece is placed on the water-soluble adhesive. The water-soluble adhesive is hardened so as to, fix the workpiece on the base. The workpiece is diced to form cut pieces. The hardened water-soluble adhesive dissolves in water. The present method reduces the deformation of the hardened water-soluble adhesive and may thus eliminate chipping. Accordingly, the present method can contribute significantly to improving the production yield.

Abstract: A lens (10) and a method for forming the lens (10). The lens (10) including a base (12) with plurality of nano-particles (14) therein. The base (12) is made of glass. The nano-particles (14) can filter infrared rays from incoming light and are evenly distribute throughout the base. The method for forming a lens includes: (1) preparing a glass pre-form (60) with nano-particles (14) for filtrating infrared rays; (2) pressing the glass pre-form (60) using a press mold machine (500) to mold a lens (10).

Abstract: A method for manufacturing a heat pipe (10) according to one preferred embodiment includes following steps: providing a heat pipe preform (11) having an open end (13); filling working liquid (14) in the heat pipe preform; and sealing the open end of the heat pipe preform using a cover (12) by a friction welding process.

Abstract: An exemplary method for manufacturing a mold core includes steps of: providing a mold core preform having a molding surface; ultrasonically cleaning the molding surface of the mold core preform; cleansing the molding surface of the mold core preform using plasma; forming a silicon carbide film on the molding surface of the mold core perform using a sputtering process; and forming a diamond-like carbon film on the silicon carbide film using a sputtering process. The mold core made by the method has excellent hardness, compressive strength, and easy separability, low manufacturing and replacement cost.

Abstract: A vacuum vapor deposition apparatus (100) for depositing materials on workpieces includes a vacuum chamber (10), a holding mechanism (20), at least two source material containing devices (30, 40), and at least two adjusting masks (50, 60). The holding mechanism is configured for holding the workpieces, and the holding mechanism is disposed in the vacuum chamber. The source material containing devices are disposed opposite to the holding mechanism in the vacuum chamber. The adjusting masks is rotatably disposed between the holding mechanism and the source material containing devices in the vacuum chamber.

Abstract: An affixing machine (100) for adhering an adhesive tape (30) to a workpiece (20) includes a base (11), a clamp (13), and a pressing element (14). The workpiece is secured in the clamp, and the clamp that is combined with the workpiece is located on the base. The adhesive tape is laid over the clamp. The pressing element is elastomeric and thereby configured for deforming the adhesive tape sufficiently to achieve a substantially contact between the workpiece and the adhesive tape.
