Comprehensive introduction of PCB cleaning machine
PCB cleaning machine is mainly used before the solder paste printing or coating production of SMT production line. Its main functions include removing tiny contamination particles and eliminating static electricity on the surface of PCB. By removing or reducing the static electricity on the surface of PCB, the interference and damage of static electricity on the circuit are reduced, thereby improving the quality of product welding or coating.
Types and functions
PCB cleaning machines are mainly of two types: online and offline.
Online PCB cleaning machine: suitable for mass production, it can automatically complete the whole process of chemical cleaning, DI rinsing, wind cutting drying and drying. It is suitable for aerospace, electronics, medical, new energy, mining and automobile fields, with the characteristics of environmental protection and energy saving, multi-function integration, and full process visualization.
Offline PCB cleaning machine: suitable for small batch and multi-variety production, it can automatically complete the whole process of cleaning, rinsing and drying. It is also suitable for multiple fields, with the characteristics of environmental protection and energy saving, multi-function integration, and full process visualization.
Working principle and application scenarios
The working principle of PCB cleaning machine is to remove pollutants on the surface of PCB by physical and chemical methods. Common cleaning methods include brush rolling, silicone adhesion and electrostatic blowing. These methods can easily remove tiny contaminants and particles on the surface of the PCB to ensure the cleanliness of the board. Maintenance and care In order to ensure the long-term stable operation of the PCB cleaning machine, regular maintenance and care are required: Clean the brush and silicone adhesive roller: Clean the brush and silicone adhesive roller regularly to prevent clogging. Check the static elimination device: Ensure that the static elimination device works properly to prevent static electricity from interfering with the circuit. Check the conveyor belt and guide rails: Check the wear of the conveyor belt and guide rails regularly to ensure smooth transmission. Replace the cleaning paper: Replace the sticky paper roll regularly to prevent the cleaning effect from decreasing. The above maintenance and care measures can extend the service life of the PCB cleaning machine and ensure its stable operation.
