Description

Technical Field

[0001] The utility model belongs to the field of PCB board processing, in particular to a plasma cleaning machine for PCB board processing. Background Art

[0002] During the plasma cleaning process, the active components of the plasma, such as free electrons, ions, and active groups, react chemically with the pollutants on the surface of the object being cleaned, thereby achieving the purpose of cleaning.

[0003] In the PCB manufacturing process, especially for rigid-flexible printed circuit boards, plasma treatment can effectively clean the drilling stains generated during drilling, including drilling stains of FR-4 and PI (polyimide) materials.

[0004] After processing the PCB board, you need to open the door of the cleaning machine and pull out the internal tray by hand before you can take out the PCB board placed on the tray. During this process, external pollutants may enter the cleaning machine and adhere to it, causing the cleaning machine to be unable to keep clean. Utility Model Content
