The PCB cleaning improves both lifespan and reliability of products. Electrical parameters of electronic components are able to improve through purification. Therefore, consistent control regarding cleaning baths are critical in the whole cleaning.
PCB cleaning involves one or more water-based rinsing steps, which is often carried out in spray cleaning systems. In consequence, the volume and density of cleaning liquids sprayed out from nozzles should be measured accurately.
Water-based and anhydrous (non-water) cleaners are commonly used. Water-based cleaners are preferred for no flash point and contain low levels of volatile organic compounds (VOCs).
Years of experience have shown that Lonnmeter concentration meters are highly reliable for controlling bath liquid concentration, ensuring the correct cleaning chemical levels. These meters provide real-time data and permanent data logging, which are crucial for maintaining high product quality and avoiding defects.
Lonnmeter inline chemical concentration meters are used to monitor the concentration of bath cleaning liquids in real-time. The output readings are displayed online and can be directly transferred to the process control system. This allows for a quick response to any deviation. For instance, refilling or replacing the bath solution for better cleaning and to avoid quality fluctuations during the cleaning process.
Benefits of Lonnmeter Liquid Concentration Meter:
Lonnmeter density and concentration meters are installed in the circulation loop just after the pump in typical or in the cleaning or rinsing tank directly. The sensor’s electronic components are housed in a durable casing, making them suitable for cleaning process systems that use high-pressure cleaners. In addition, the online concentration meter can be installed in hazardous areas where non-water-based cleaning agents are used.
Measurement Ranges:
By accurately measuring the concentration and temperature of cleaning bath container, Lonnmeter helps ensure that the cleaning process remains consistent and efficient, reducing the risk of damage to the PCB and enhancing overall product quality.
