Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a cleaning device for PCB board production. Background Technology

[0002] PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical connections. Cleaning is a crucial process in PCB production. During the initial soldering stage, PCBs are prone to contamination with liquids and other impurities such as dust, all of which need to be removed. However, traditional cleaning methods, which involve cleaning the PCB on a flat surface, often result in incomplete cleaning. The back side of the PCB, placed on a flat surface, is difficult to clean thoroughly, potentially affecting subsequent PCB processing. Therefore, a cleaning device for PCB production needs to be designed to address this issue. Utility Model Content

[0003] The purpose of this invention is to provide a cleaning device for PCB board production to solve the problems mentioned in the background art.
