摘要:
A multi-chip module is provided with a structure for disposing of a large amount of surplus solder at soldered portions. In this multi-chip module, a cooling member (structure) is soldered directly at the back side of heat generating member such as a semiconductor integrated circuit element. In order to dispose of the surplus solder, the present invention has a first metallized part formed at a cooling member which is larger than a second metallized part formed at the back side of semiconductor integrated circuit element which is solder with the first metallized part.

The present invention provides a method for removing solder adhering to an LSI. In this method, a plate-shaped first member for causing molten solder to adhere thereto is mounted on top of a heater. An LSI is placed on top of the first member with the surface on which solder is attached facing downward. A second member for adding a load to the LSI is placed on top of the LSI. The heater is heated up to heat the first member and the LSI, and to melt the solder. The molten solder is transferred to the first member. A suction mechanism is positioned at a location a predetermined distance away from the top surface of the second member. The second member and the LSI are attracted by the suction mechanism, and the LSI is pulled away from the first member. The solder is thereby removed from the LSI.

A solder-removing apparatus includes a heating portion for heating the object having the solder adhered thereto, a measuring portion for measuring the distance from the measuring portion to the object, a solder-drawing portion for drawing the molten solder on the object by suction, an X-Y moving portion for moving the object in an X-direction or a Y-direction, a Z moving portion for moving the object relative to the solder-drawing portion in a Z-direction, and a control portion for controlling the X-Y moving portion and the Z moving portion. During the time when the molten solder on the object is drawn by the solder-drawing portion, the control portion causes the X-Y moving portion to move the object, and also causes the Z moving portion to move the object relative to the solder-drawing portion in accordance with the distance, measured by the measuring portion, so that the distance between the solder-drawing portion and the object can be kept constant.

The present invention relates to a method and apparatus for producing a reference image (template) used in a glass bottle inspecting apparatus for detecting a defect at a specific location of a bottle-mouth portion and the like of a glass bottle, and used for being compared with the image obtained from the glass bottle to be inspected in the inspecting apparatus. According to a method of producing a reference image of the present invention, plural images are formed by using a CCD camera to image a plurality of glass bottles as samples which may contain defective glass bottles, and a reference image is provided from the obtained plural images, a range of brightness when light is applied to a non-defective glass bottle being specified in said reference image.
摘要:
A glass bottle inspecting apparatus is presented which can detect a defect at a specific location of a bottle-mouth portion of a glass bottle. An inspecting apparatus detects a defect of a glass bottle by imaging light from the glass bottle while the glass bottle (2) is illuminated and rotated, and processes the obtained image. A glass bottle inspecting apparatus includes a lighting device (7) disposed at a predetermined position with respect to the glass bottle, a plurality of CCD cameras (11-20) disposed around the glass bottle for imaging a specific part of the glass bottle, an angle detection device (10) for detecting a rotation angle of the glass bottle with respect to a reference position, and an image processor (8) for processing the images obtained by the CCD cameras. The image processor stores rotation angle information detected by the angle detection device in such a manner that the rotation angle information corresponds to the image imaged by each of the CCD cameras.

A laser printing apparatus is formed by a laser oscillator 10, galvano mirrors 42, 44 for scanning the laser light emitted from the laser oscillator 10, and an f&thgr; lens 40 for focusing the laser light emitted from the laser oscillator 10 on MCCs 32, 34 serving as the member to be printed. The laser oscillator 10 is an YLF laser oscillator which emits the laser light of the third harmonics in the ultraviolet range. The laser printing is performed on the MCCs 32, 34 serving as the member to be printed by using the laser light emitted from the laser oscillator 10.
