Abstract: A bonding apparatus comprises a movable bond head collet, a reference marker configured to move with the bond head collet, a flip head collet, first and second imaging devices and an adjusting mechanism. In use, the first imaging device captures one or more images of the reference marker and the flip head collet, and the second imaging device captures one or more images of the reference marker and the bond head collet. The adjusting mechanism aligns a position of the bond head collet with a position of the flip head collet based on an offset that is determined from the images of the flip head collet, bond head collet and reference marker. The flip head collet retrieves an electrical component and transfers the electrical component to the bond head collet at the alignment position.

Abstract: The present invention provides an apparatus for collecting and detecting liquid samples comprising a first chamber and a second chamber. The first chamber is used for collecting liquid samples for initial detection, and the second chamber is used for collecting liquid samples for second confirmatory detection. The first chamber and second chamber of the apparatus are detachable. When a second confirmatory detection is necessary, the second chamber can be separated from the first chamber, and then sent to a detection agency for confirmatory detection. It can avoid the contamination of liquid samples caused by contacting with test strip of a traditional apparatus; thus, it can effectively reduce the space required for storing liquid samples and greatly reduce the risk of leakage of liquid sampled during transportation.

Abstract: A basic oxygen furnace slag treatment method includes the steps of mixing basic oxygen furnace slag with an active aqueous solution and then keeping the mixture thus obtained under an enclosed environment for reaction and then employing a solid-liquid separation procedure to separate solid phase from liquid phase. Since basic oxygen furnace slag has strong alkaline, the method of the invention overcomes the problem that directly discharging basic oxygen furnace slag will cause environmental pollutions. The basic oxygen furnace slag treatment method avoids a secondary pollution, and can turn waste into treasure, bringing a number of economic benefits.
