Abstract: A circuit board cleaning apparatus (10) is disclosed which efficiently cleans a circuit board (12). The circuit board is positioned beneath a head assembly (24) whre it is grasped by a number of arms (38) and lowered into the interior of a tank (26). The board is oscillated about a vertical axis within the tank while immersed in a cleaning agent, such as water. Provisions are made to rinse the cleaned board and dry the board. After the board has been cleaned, it is removed from the tank and released. All cleaning, rinsing and drying operations are conducted within the tank.
