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.
Claims10
A method for cleaning a circuit board, comprising the steps of:
- exposing the circuit board to a liquid cleaning agent;
- moving the circuit board within the liquid cleaning agent to induce relative motion between the liquid cleaning agent and the circuit board to clean the circuit board, said circuit board having a circuit board plane coinciding with the major dimensions of the board, the direction of movement of the circuit board within the liquid cleaning agent lying substantially within the circuit board plane;
- and
- separating the cleaned circuit board and liquid cleaning agent.
