[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher density installations, and also help reduce assembly processes and enhance reliability. However, the surface must be kept clean and free of dust and impurities during use.

[0003] In the prior art, the flexible circuit boards are cleaned by placing them one by one in a device, and after they are fixed, they are manually cleaned by a convenient cleaning tool. In this way, the cleaning of the flexible circuit boards can be completed to a large extent.

Secondly, after the cleaning is completed, they need to be neatly stacked one by one to facilitate subsequent transportation and processing. This also increases the workload of the staff and reduces the processing efficiency. Therefore, an FPC flexible circuit board cleaning device is introduced. Utility Model Content
