Abstract: A pick and place machine is described which uses an imprint left in a layer of fluid by a component that has been dipped in the fluid to guide a placement process. An apparatus for placing a component is disclosed, which includes a surface that receives a layer of fluid, an imprint of a component in the layer of fluid, and a camera that captures an image of the imprint in the fluid. A method of placing a component with a pick and place machine is disclosed which includes dipping a component in a layer of fluid, capturing an image of the layer of fluid, analyzing the image of the layer of fluid, and placing the component based on results of the analysis of the image of the layer of fluid. The image can be used to determine the status of the component or where to place the component.

Abstract: A capillary tube (1) for bonding wire (5) has a bore (3) and a cross section in a direction normal to the bore having a long dimension and a short dimension in a direction normal to the long dimension. The bond is made to bond pads (9) using the capillary tube by bonding a wire to one bond pad while the capillary is oriented with the long dimension (25 to 27 or 35 to 37) in a first direction and bonding a wire to a die immediately adjacent the one bond pad with the capillary which can be oriented with the long dimension in the same direction or in a direction normal to the first direction, as may be required.
