Abstract: PURPOSE:To perform die bonding or wire bonding by providing a bonding material supply head, by providing a component fitting head and a wire bonding head on an X-Y table, by collating a pick-up output of a TV camera with a standard to correct deviations, and by conduct switching automatically according to the correction. CONSTITUTION:A position to which a component is fitted is detected automatically, a supply head is guided to a normal position, and a bonding material is supplied therefrom. Thereafter a circuit board is conveyed to a position at which it is fitted with components. A TV camera 9, a turret-type fitting head and a wire bonding head 23 are fitted on a block 21 which is fixed on an X-Y table. A pick-up output of the TV camera 9 is collated with a standard, deviations, if any, are corrected automatically, a desired head is selected to be fitted with a component. Next, when said board is forwarded under the bonding head 23, a wire is guided from a spool 20, via a guide 24, to a capillary 27 fixed to an arm 28 forming a supersonic horn, through the intermediary of clampers 25 and 26, and the head 23 is moved vertically to execute wire bonding. By this constitution, bonding dropping, component fitting and wire bonding can be executed sequentially and consecutively in a full-automatic and efficient manner.

Abstract: PURPOSE:To obtain a mounting system applying a bonding material smoothly in a full-automatic manner by a constitution wherein informations obtained by picking up by a camera set on a supply head are collated with standards to calculate positional deviations and the head is driven to a proper position so as to supply the bonding material. CONSTITUTION:When circuit boards 21 and 22 get from a magazine 2 to positions under a supply head 5 installed on an X-Y table 26, marks 23 and 24 are picked up by a TV camera 6, subjected to image processing 30 and then inputted to CPU28, wherein they are collated with standards to calculate deviations. Based on this calculation, the head 5 is moved to a proper position, and Ag paste is injected to drip from a needle 26 positioned at the end of a cylinder 25, by controlling a solenoid-operated valve 29. According to this construction, the Ag paste can be supplied onto the boards in a successive and full-automatic manner, and the productivity is further improved to a great extent by incorporating a chip fitting process also into the same process.

Abstract: PURPOSE:To prevent the adjoining bonding wires to come in contact with each other by a method wherein, in an area which is electrically independent, a wire bonding operation is performed in the direction where a new bonding will be conducted. CONSTITUTION:An electrically independent area 6 consisting of a metal foil of the same material as lead frames 4a and 4b is provided in advance in parallel with the side 2b of a semiconductor chip 2. After the bonding operation for the final bonding pad 3a along a side 2a and the lead frame 4a has been finished, the direction of bonding operation of a capillary is changed to the direction of bonding operation between a bonding pad 3b along the side 2b and the lead frame 4b, and a bonding operation is performed in the area 6. Subsequently, a wire bonding between the bonding pad 3b and the lead frame 4b is conducted along the side 2b.
