摘要:
An apparatus, particularly a chuck for retaining a thin part for micro-machining processing, is disclosed. The chuck is formed of a plate-shaped body having a first surface and a second surface opposite the first surface. The plate-shaped body includes a light-transmissive material, and at least one of the first surface or the second surface is a roughened surface. The chuck can be incorporated into a micro-machining system using a chuck support that allows light through to backlight a processed part for inspection.

Apparatuses of manufacturing semiconductor packages are provided. An apparatus includes a chuck having a body, a porous plate disposed on the body, and a buffer pad disposed on the plate to provide a place on which a plurality of chips are loaded. The buffer pad has elasticity greater than the plate. The apparatus also includes a vacuum part supplying vacuum to the chuck so that the plurality of chips are sucked onto the buffer pad. Methods of manufacturing semiconductor packages using the apparatus are also provided.
摘要:
A method for centering a circular optical element using a non-self-centering chuck adapted to grip the element at two grip strengths. The element is rotated in the chuck while measuring the lateral position of the element's outer rim with a probe. The positions of maximum and minimum run-out of the element as a function of its angular position are determined. Chuck rotation is stopped at an angular position with the maximum rim run-out positioned at a predetermined point. The grip of the chuck is reduced such that the element is still held in the chuck but can be moved in a lateral direction without damaging its surface. The element is moved in a direction connecting the predetermined point of maximum run-out and the axis of rotation of the chuck, in order to reduce the run-out of the element. The procedure is repeated until the desired centering is achieved.
