Abstract
In a case for housing an electronic circuit board, the opening edge of the case body is formed with a prescribed distance below the board mounting surface. The board is fastened on the mount of the case body with the fastening means. The case body is then inverted and is placed over a rising coating bath, and then the coating bath is raised close to the opening edge such that the board is dipped in the coating liquid and is coated. By this, application of the coating liquid to prescribed regions constituting coating-prohibited regions of the case body can be prevented. Cost can therefore be kept down and complication of the processing steps prevented because no masking of the case body is necessary. Moreover, the reliability of the electronic circuit unit can be enhanced and the need for a jib is eliminated. This helps to avoid complication of the fabrication process and makes another contribution to cost control.
