Title: Visual inspection of soldered state
Inventor: HAMADA OSAO
IPC: G01B11/24
Filed: 1993-09-27
Abstract: PURPOSE:To provide a visual inspection method for a soldering state wherein a non-solder state can be inspected without considering a position dislocation of an object to be inspected. CONSTITUTION:An image processing part 5 previously inputs part size, registers a master pattern composed of a three-dimensional shape pattern of a soldered part in a state mounted on a printed wiring board P on the basis of the part size and sets a search area including the soldered part. In an inspection process, scanning is performed by a three-dimensional sensor 1 on the basis of search are data, three-dimensional image data are obtained in the search area, thereafter, they are collated with the master pattern and the maximum matching rate is found. The maximum matching rate is compared with a level number value which is judged to be non-soldering and defective, and if the maximum matching rate is larger than the level judged to be defective, it is judged to be defective as non-soldering considering as the shape is similar.

IPC: H01L21/60
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a land for wire-bonding responding to narrower pitches with which degradation of a bondability of Au wire bonding due to oxidation of wires composed of base metal formed on a circuit board is prevented in a method of electrically connecting a semiconductor element and a circuit board with a lead composed of Au formed by wire bonding. SOLUTION: When wiring 4 a circuit board 1, wedge bonding is performed at a room temperature to form a land 5 composed of Au. Then, Au wire ball bonding is performed assuming an electrode 3a of a semiconductor element 3 as a primary side and the land 5 as a secondary side to form a lead 10 and electrically connect the electrode 3a and the land 5. Since the land 5 is formed by wedge boding, the land can be formed in a size about the same as a slightly squashed Au wire 6. Since wedge bonding is performed at a room temperature, the wire 4 of the circuit board 1 is not oxidized when the land 5 is formed.

IPC: B22D35/00
Filed: 1986-10-11
Abstract: PURPOSE:To admit a molten metal in the form of laminar flow into a tilting holding furnace and to prevent the intrusion of air therein by controlling the tapping rate of the molten metal from a stationary holding furnace by the differential value between the required molten metal flow rates and actual flow rates of a downstream guiding through and upper stream guiding trough. CONSTITUTION:The molten metal flow rate of the downstream guiding trough 4 is detected by a level detector 7 and is inputted to a controller 8 with an arithmetic function by which the flow rate is compared and operated with the set flow rate value so set as to allow the molten metal to flow down in the form of the laminar flow at a desired velocity of flow. The differential value thereof is outputted to a tilting device 9 to actuate the lifting cylinder and rotating mechanism of the device 9 in the directions to lower the tilting holding furnace 5 and to return the inclination to the original position so as to maintain the flow rate within the range of the set value. The difference in the molten metal level in the guiding trough 4 and the holding furnace 5 is thereby maintained within an adequate range and the molten metal is run in the form of the laminar flow in the holding furnace 5. The flow down of the molten metal like a fall and the intrusion of the air therein are thus prevented.

Abstract: PURPOSE:To output a sawtooth wave by using a control signal outputted from a microcomputer so as to apply charge/discharge control to a charge/discharge capacitor. CONSTITUTION:When a pulse 1 whose duty ratio is 50% is inputted to an input terminal (a) for one cycle, transistors(TRs) 7,8 are turned on for a time when no control signal b1 is inputted to an input terminal (b) and a TR 4 is turned off.

A control signal a1 inputted to the terminal (a) in a next timing goes to 0, TRs 7, 8 are turned off and a voltage of the capacitor 3 is kept while the signal b1 is 0. Then the operation above is repeated till the input signal from the terminal (b) goes to 1 and a voltage across the capacitor 3 reaches an output voltage V. When the signal b1 goes to 1, the TR 4 is turned on and the charge in the capacitor 3 is discharged through the resistor 12, a sawtooth wave output voltage C1 whose amplitude is V is outputted across the capacitor 3 within a set time.
