    摘要: A semiautomatic method for digital feature separation uses a trained sample selected by an operator using a software “eye dropper” tool or a similar region-of-interest tool to sample features of interest on a stored digital image of, for example, an electronic component such as pads, bumps or leads of the component. Pixels from the sampled features are analyzed and plotted based on their color hue and saturation values or gray scale intensity values. The range of such values is chosen by a user. A second digital image is then compared to the sampled feature data gathered by the “eye dropper” tool. If the color and intensity values of the pixels from the second digital image fall within a user defined acceptable absolute value range, then the locations and values of those pixels in the image are saved. Background or surrounding elements in the second digital image which do not fall within the acceptable value range are deleted and replaced with a code that makes these background or surrounding element locations appear as a graphic transparency. This process leaves only the features of interest in their original locations saved in the graphics memory surrounded by pixels that have been made video transparent. The resulting saved image which contains only the selected features is then laid over a live image such as that of a target substrate with corresponding features of interest. The operator then manually aligns the saved features from the component image over the corresponding features of the live image of the substrate to achieve component to substrate registration.

    摘要: The present invention provides for the accurate placement of an object having a surface pattern by relating the perimeter of the object to the surface pattern, such as a circuit pattern of a semiconductor die. This includes illuminating the object at its front and rear faces and viewing the object with a machine vision system. Front-side illumination of the surface pattern enables the machine vision system to obtain an image of the actual position of the circuit pattern or other pattern of interest on the front of the component. Rear illumination provides a silhouette of the perimeter edges of the component enabling the machine vision system to obtain the actual position of the perimeter edges of the component. A corrective offset from a normative feature location, such as the centroid defined by the perimeter edges of the component, is then calculated. The machine vision system is coupled to a conventional automatic component placement system that uses an in-flight perimeter registration and orientation system. The corrective offset from the machine vision system is used to adjust the position calculated by the conventional perimeter registration system to precisely place the component with respect to features of interest on the component, such as the center of the circuit pattern, rather than the mere outline of the component.

    摘要: A method and apparatus for component to substrate assembly permits in situ reflow of a flip chip (or other suitable component) in a manner which promotes proper settling of the component as solder begins to flow at the contact points between the component and the substrate. The pick-up head of a placement machine heats the component while applying up to several grams of downward force that serves to level the component. The downward force (downforce) is accurately measured using an electronic force sensor such as a strain gauge, force sensitive resistor, or any other suitable type of force sensor. The initiation of solder reflow can be detected with the pick-up head by sensing a decrease in the downforce. At this instant, the downforce applied to the component with the pick-up head is decreased preferably to zero and the vacuum or other retention mechanism holding the component is then released, freeing the component from the pick-up head and permitting the component to properly self-center using the liquid solder's surface tension. Further, at the instant that solder reflow is detected, the pick-up head may optionally be displaced a short distance from the component. However, because the pick-up head must (where it is used to supply heat) continue to supply heat to complete the reflow of the solder, it is only displaced a minimal distance from the component so that heating by radiation continues to reflow the solder while the pick-up head is displaced from the chip. The approach is applicable to other assembly processes where downforce is helpful to stabilize a component prior to final bonding and a change in measured downforce indicated the beginning of melting, curing or another process which indicates that downforce can be removed.

    摘要: An "on-the-fly" component registration system comprises a two-dimensional imaging camera carried by a component placement nozzle platform in turn carried by a positioning gantry. A reflective surface located on or adjacent to a workpiece on which a component is to be placed allows the camera to image by reflection therefrom the component held by the component placement nozzle and an associated machine vision system to determine position correction information (e.g., .DELTA.x, .DELTA.y and .DELTA..theta.) therefrom while the component placement nozzle platform is traveling on the positioning gantry from a component supply station, by the reflective surface, on the way to a component placement target position on the workpiece.

    摘要: A smart camera system provides focused images to an operator at a host computer by processing digital images at the imaging location prior to sending them to the host computer. The smart camera has a resident digital signal processor for preprocessing digital images prior to transmitting the images to the host. The preprocessing includes image feature extraction and filtering, convolution and deconvolution methods, correction of parallax and perspective image error and image compression. Compression of the digital images in the smart camera at the imaging location permits the transmission of very high resolution color or high resolution grayscale images at real-time frame rates such as 30 frames per second over a high speed serial bus to a host computer or to any other node on the network, including any remote address on the Internet.
