Abstract
An electronic circuit board rework and repair system having a carriage manually movable to successive station positions and having a table thereon movable along mutually orthogonal axes for positioning of a circuit board clamped to the table. At a first station, a circuit board is loaded onto the table, and a microscope can be swung into position for inspection of the loaded board. At a second station, an intended component or circuit board site can be aligned by way of a visual image of the component and site, and the table locked in position. At a third station, the selected component or circuit board site is automatically in alignment with a programmable heater for selected heating of the component contacts and removal of the component by a pickup probe associated with the heater. The system is calibrated such that there is alignment between a visually established position at the second station and that component position under the heater at the third station. Components can also be attached to selected sites of a circuit board by operation of the system.
