Abstract

The invention discloses a printed circuit board assembly (PCBA) on-line cleaning machine which comprises a machine body. A mesh belt for transmitting a PCBA board is arranged in the machine body, and a chemical pre-cleaning room, a chemical cleaning chamber, a chemical diaphragm chamber, a digitally integrated (DI) water pre-cleaning chamber, a DI water rinsing chamber, a spraying chamber, a wind shear drying chamber and a hot air drying chamber are arranged above the mesh belt and sequentially arranged along the operation direction of the mesh belt. The PCBA on-line cleaning machine drives the PCBA board through the mesh belt to sequentially perform chemical pre-cleaning, chemical cleaning, chemical isolation, DI water pre-rinsing, DI water rinsing, spraying, wind shear drying, hot air drying and the like from left to right, achieves full-automatic on-line cleaning of the PCBA board, enables the PCBA board to be comprehensively cleaned and rinsed and improves the cleaning and rinsing quality.

Description

Technical field: [0001] The invention belongs to PCBA cleaning equipment, in particular to a PCBA online cleaning machine. Background technique: [0002] PCBA (Printed Circuit Board Assembly) is the whole process of PCB empty board passing through SMT and then DIP plug-in. The PCB board after the above process is called PCBA. Flux to remove oxides and reduce the surface tension of the material to be welded, but in this process, there will be some flux residues on the board, and these residual fluxes are easy to absorb oil, dust, etc. in the subsequent process, which is harmful to the PCB board adverse effects and consequences of their work. [0003] In order to ensure the quality of the PCB board and avoid the residual flux from absorbing oil and dust, it is usually necessary to clean the PCBA or use no-clean flux in the SMT process, but with the miniaturization and diversification of functions of electronic products, I / The quantity of O is constantly increasing, the pitc...
