A component mounting system includes first to third (pickup, transfer, and placement) stations. A component supplied at a component supply is picked up by a transport head at the pickup station and then transferred to a placement head at the transfer station. The placement head carries the component to the placement station where the component is placed and mounted onto a substrate such as a circuit board. The component, when held by the placement head, is recognized by an imaging device at or in the vicinity of the transfer station.

In component mounting process for a plurality of components to be mounted onto a board, a plurality of bump electrode portions formed on mounting-side surfaces of the components to be mounted onto the board are brought into contact with a bonding-assistant agent so that the bonding-assistant agent is supplied thereto to allow the bonding-assistant agent-supplied components to be mounted onto the board, the component mounting process includes, supplying the bonding-assistant agent to a first component among the plurality of components, and starting the supply of the bonding-assistant agent to a second component among the plurality of components before completion of the mounting of the bonding-assistant agent-supplied first component onto the board.

Component mounting method

After detection of contact between respective solder bumps of an electronic component, sucked and held by a suction nozzle of a head tool, and respective solder portions of a circuit board, the solder bumps and the solder portions are melted by heating. Releasing of the electronic component from suction and holding by the suction nozzle of the head tool is performed, not at a time during solder melting, but at a time after the solder is melted, cooled and solidified. Thus, an electronic component mounting method and apparatus capable of mounting high-end electronic components having narrow-pitched bumps are provided.

Apparatus and method for mounting electronic components

In a component mounting apparatus in which integrated components having a chip-on-chip structure are formed by mounting upper chips on lower chips. The lower chips picked up from a component carrying-in unit by a component carrying-in head are placed on a mounting stage, and the upper chips picked up from a second component tray by a component transporting head are vertically flipped around a rotation axis and transferred to a mounting head at a component transferring position, then the upper chips held by the mounting head are descended and mounted by solder bonding on the lower chips held by the mounting stage at a component mounting position. Integrated components formed by mounting are carried out of the mounting stage by the component transporting head and stored in a first component tray in a component storing unit.

Component mounting apparatus and component mounting method

A component-mounted substrate moved to a specified substrate position by a substrate holding-and-moving device is delivered from a top of the substrate holding-and-moving device to a substrate discharge holder, and then while the substrate discharge holder is not moved, the substrate holding-and-moving device is moved to another substrate position, where a new substrate is received. Consequently, a later-executed movement operation for moving the new substrate to a substrate mounting region by the substrate holding-and-moving device, and a transfer operation for transferring the component-mounted substrate to an unloader unit by the substrate discharge holder, may be performed in parallel with each other without being influenced by each other's operation.

Apparatus and method for mounting component

A component mounting apparatus includes a component holding and conveying device for holding and conveying a component and mounting the component onto a circuit board, a circuit board holding device for holding the circuit board, an image recognition optical system for performing recognition of the component and the circuit board with different fields of view, respectively, and a control section. The control section repeatedly determines an optical axis shift amount with the two fields of view between a position of the component and a position of the circuit board recognized by the image recognition optical system. Based on these determination results, the control section determines an optical axis shift amount for calibration, wherein calibration of the image recognition optical system is performed based on the optical-axis shift amount for calibration determined by the control section. Then, the component is mounted onto the circuit board.

Component mounting apparatus and method

An image forming apparatus according to the present invention includes: a photosensitive body; an exposing device for irradiating the photosensitive body with a light to form a latent image on the photosensitive body; a developing device for developing the latent image formed on the photosensitive body to form a developer image; a transfer roller for transferring the developer image on a recording paper; a fixing device for thermally fixing a transferred image on the recording paper after image transference; and a case for accommodating the photosensitive body, the exposing device, the developing device, the transfer roller and the fixing device, the case having at least six planes, two or more of the planes provided around an axis of the photosensitive body, being placement planes which are usable as a bottom during an image forming operation. The fixing device is always above the photosensitive body and the developing device, regardless of which plane is selected from the two or more placement planes as a bottom when the apparatus performs the image forming operation.
