Circuit board equipment pump refers to the pump used in printed circuit board (PCB) manufacturing equipment to transport chemical liquids or cleaning fluids to ensure the smooth progress of the manufacturing process. The production of circuit boards involves many chemical processes (such as etching, coating, cleaning, etc.), and the role of the pump is to accurately and safely transport various solutions or liquids to avoid adverse effects of chemicals on the circuit board. Circuit board pumps typically offer corrosion resistance, precise control, and high stability.
Introduction: The in-tank pump of circuit board equipment is a special pump used in the manufacturing process of printed circuit board (PCB), which is used for liquid circulation, mixing and transportation in various chemical tanks. The in-tank pump is immersed, usually fixed above the tank, through the pump head deep into the tank to achieve liquid circulation and treatment. The in-tank pump can not only effectively stir the liquid in the tank, ensure the uniform concentration of the chemical solution, but also help to achieve the filtration and transportation of the liquid in the tank.
Feature:
Strong corrosion resistance: The chemical liquid commonly used in the production process of the circuit board is highly corrosive, so the pump in the tank is generally made of polymer materials (such as PP, PVDF, etc.), and has excellent acid and alkali resistance and corrosion resistance.
High temperature resistance: In-tank pumps usually need to adapt to the use of higher temperature environments, especially in hot dip plating, etching and other processes, need to be able to withstand 60 ° C to 90 ° C or even higher temperatures.
Good sealing performance: Since the pump in the tank is immersed in liquid, sealing performance is critical to prevent liquid leakage affecting the equipment and the environment.
Simple structure, easy maintenance: The tank pump design is compact, easy to install, maintenance is also more convenient, suitable for long-term continuous operation.
Type:
Magnetic drive tank pump: through magnetic coupling drive, avoid shaft seal leakage, suitable for no leakage requirements.
Mechanical seal tank pump: the use of mechanical seals, suitable for high pressure conditions, but the relative maintenance cost is slightly higher.
Non-sealed tank pump: such as air lift pump, the use of air to drive liquid flow, no sealing structure.
