プリント基板が得られる利点がある。As explained above, the first aspect of the present invention is to transport the printed circuit board after soldering by the transport means, and after cleaning the lower surface of the printed circuit board with a roll blank containing a cleaning liquid, pressurize the printed circuit board. The cleaning liquid adhering to the printed circuit board is removed by blowing air, and then the printed circuit board is lowered, and then the cleaning liquid is removed in the opposite direction to the running direction of the printed circuit board and in the direction crossing the running direction of the printed circuit board. The printed circuit board is cleaned by immersing it in a cleaning solution that is jetted at each step.Then, when the printed circuit board is raised, the cleaning solution is sprayed to clean the top and bottom surfaces of the printed circuit board.Then, the printed circuit board is cleaned by spraying pressurized air. Since the cleaning liquid adhering to the substrate is removed, the printed circuit board is then dried with hot air, and then cooled with cold air, the printed circuit board is completely cleaned and there is an advantage that a high quality printed circuit board can be obtained.

を有する。Further, a second aspect of the present invention provides a conveying means for conveying a printed circuit board after soldering; a brush cleaning device having a cleaning tank containing a cleaning liquid and a roll brush for cleaning the lower surface of the printed circuit board; A liquid removal device that uses pressurized air to remove the cleaning liquid adhering to the board; and a jet tube that jets the cleaning liquid in a direction opposite to the running direction of the printed circuit board and in a direction that intersects with the running direction of the printed board. , an immersion cleaning tank that cleans the printed circuit board by lowering it into the cleaning solution jetted from these jet tubes, and a jetting tube that sprays the cleaning solution toward the top and bottom surfaces of the printed circuit board when the printed circuit board is raised. an immersion/shower cleaning device that is equipped with a shower cleaning device that performs cleaning with cleaning liquid ejected from these jetting pipes; a hot air drying device that uses hot air to dry the cleaning liquid adhering to the printed circuit board; and a heated printed circuit board. A cooling device that uses cold air to cool the PCB is installed in sequence in the running direction of the printed circuit board, so large contaminants such as flux and metal powder attached to the printed circuit board do not get mixed into the next-stage cleaning solution. ,
Since the printed circuit board is cleaned with a clean cleaning liquid every time the printed circuit board is cleaned, dirt on the printed circuit board is completely removed, and there are advantages such as less waste of the cleaning liquid and economical performance.
