Abstract: A method for bonding a heat sink to a chip package structure is disclosed. The chip package structure at least comprises a chip and a stiffener ring around the chip. Both the chip and the stiffener ring are set up on a substrate. The heat sink comprises a first protruding section located at a position corresponding to the chip and a plurality of second protruding sections located at positions corresponding to the stiffener ring. The method includes forming a gluing layer on the first protruding section and the second protruding sections of the heat sink and pressing the heat sink against the chip package structure to bond the heat sink and the chip package together.

Abstract: A coating apparatus and method are disclosed in which even if poor coating occurs in a lower-layer, no poor coating occurs in an upper-layer formed on the lower-layer. A pre-wet liquid coating device is disposed between a first coating device at the upstream side of a support web conveying direction, and a second coating device disposed at the downstream side. When an uncoated portion is formed by the first coating device, a pre-wet liquid is coated by a pre-wet liquid coating device, and the coating liquid can be reliably coated by the second coating device. When the pre-wet liquid coating device is removed from the support web, first, the pre-wet liquid coating device is brought into liquid-running out state, and thereafter, removed from the support web. Accordingly, the pool of pre-wet liquid is eliminated and occurrence of a thickly coated portion on the support web can be prevented.

Abstract: A system, method and apparatus for collecting overspray from single color coating applications. Within a spraying area are one or more curtains. The curtains are continuously coated on one side with the material to be sprayed through material dispensers aimed at the upper region of the panel curtains. The material dispensers coat the panel curtains so that material runs down the panel curtains and into a recycling pan. Spraying equipment is used to coat the object. The spraying occurs in the direction of the panel curtains. Thus, any overspray material from the spraying process is deposited on the panel curtains. The flowing material on the curtain collects the overspray material to and transfers it to the collection pan for re-use in the collection process. In the collection pan, one or more agitators may be used to ensure proper consistency is maintained for the material.
