2073032 9111093 PCTABS00006 Apparatus for the installation of fine pitch components onto printed circuit boards includes a component acquisition stage in which a pickup head (130) picks a component from a component acquisition area, a second stage optionally including a vision inspection camera (154) for inspecting the component to ensure placeability, and a placement stage having a placement head (20) for installing the component on a printed circuit board. The three stages operate concurrently. The placement stage has an adjustable-width board clamping and carriage mechanism (202) moveable along a longitudinal horizontal axis, and the placement head is mounted on a quill moveable laterally and horizontally along a carriage (21), the placement head being moveable vertically and rotatable about a vertical axis by the quill. The placement head passes the component over an upward-looking camera (208) to obtain positioning information. An underboard support (12) is moveable beneath the placement head to support the circuit board directly beneath the component installation location. A conveyor (6) passes boards through the system, and tongues (200) lift the boards up to the clamping and carriage mechanism. Other boards may pass through the system, under the board being worked on.
