PCBA washing process and process principle<\/p>\n\n\n\n

Principle of PCBA online washing process<\/p>\n\n\n\n

Components controlled by the speed of the conveyor belt are continuously on the conveyor belt and the production cycle time is uninterrupted cleaning method. It is suitable for the cleaning of large quantities of PCBA, and completes all processes of water-based cleaning, water-based rinsing and drying online through different cavities.<\/p>\n\n\n\n

Principle of ultrasonic cleaning process<\/p>\n\n\n\n

The batch cleaning process is the cleaning of multiple components in a controlled production time period or different batches of a component. In the batch PCBA washing process, ultrasonic cleaning is the most common cleaning method.<\/p>\n\n\n\n

Ultrasonic cleaning process:<\/p>\n\n\n\n

Features of ultrasonic cleaning process:<\/p>\n\n\n\n

The whole process of water-based cleaning, water-based rinsing, and drying is completed in one or more chambers; it can be used to clean the assembly structure with low support height and narrow bottom gap; the cleaning effect is optimized near the optimum temperature for the effectiveness of ultrasonic waves.<\/p>\n\n\n\n

Advantages of PCBA Washing Process<\/p>\n\n\n\n

  1. Safe operation, non-flammable and non-explosive<\/li>
  2. Use economy<\/li>
  3. Good compatibility with substrates and wide cleaning range<\/li>
  4. Material safety and environmental protection<\/li>
  5. It has the joint effect of multiple cleaning mechanisms<\/li>
  6. Flexible process options<\/li><\/ol>\n\n\n\n
