PCBA cleaning process introduction
1. Fully automated online cleaning machine
A fully automated online cleaning machine, which is thoroughly effective against organic and inorganic contaminants such as rosin flux, water-soluble flux, no-clean flux/solder paste, etc. on the surface after PCBA soldering of SMT/THT Of cleaning. It is suitable for large-scale PCBA cleaning. It uses safe and automated cleaning equipment to be placed on the Denso production line, and completes the chemical cleaning (or water-based cleaning), water-based rinsing, and drying processes online through different cavities.
   During the cleaning process, PCBA is cleaned in different solvents through the conveyor belt of the cleaning machine. The cleaning fluid must be compatible with components, PCB surface, metal coating, aluminum coating, labels, writing and other materials. Special parts need to consider whether they can withstand cleaning.
  The cleaning process is: board loading→chemical pre-washing→chemical cleaning→chemical isolation→pre-rinsing→rinsing→spraying→wind cutting drying→drying
  2, semi-automated offline cleaning machine

A semi-automated off-line type, the cleaning machine thoroughly and effectively cleans the rosin flux, water-soluble flux, no-clean flux/solder paste and other organic and inorganic contaminants left on the surface after smt/THT PCBA soldering . It is suitable for small batch and multi-variety PCBA cleaning. It can be set anywhere on the production line through manual handling. It can complete chemical cleaning (or water-based cleaning), water-based rinsing, and drying in a cavity offline. + e4 c2 R; A, @: N
During the cleaning process, PCBA usually needs to be fixed by a fixture or placed in a basket. The cleaning fluid must be compatible with components, PCB surface, metal coating, aluminum coating, labels, writing and other materials. Special parts need to be considered whether they can withstand Clean.
   There are certain requirements for the placement density and placement angle of PCBA in the cleaning basket. These two factors have a direct impact on the cleaning effect.
  3, manual cleaning machine
A manual cleaning machine (also called constant temperature cleaning tank), which is aimed at the residual rosin flux, water-soluble flux, rosin flux, no-clean flux/solder paste, etc. on the surface of SMT/THT PCBA after soldering. , Inorganic pollutants are thoroughly and effectively cleaned. It is suitable for the cleaning of small batch samples of PCBA. Through temperature control, it is adapted to the manual cleaning process of MPC micro-phase cleaning agent and completes the chemical cleaning in a constant temperature bath.
quality assurance
iPCB has passed ISO9001:2008, ISO14001, UL, CQC and other quality management system certifications, and produces standardized and qualified PCB products. We master complex process skills and use professional equipment such as AOI and Flying Probe to control production, X-ray inspection machines, etc. . Finally, we will use double FQC inspection of appearance to ensure shipment under IPC II standard or IPC III standard.
