(Summary description)How to verify the processing effect of the products or materials processed by the plasma cleaning machine? Is there any other method besides the well-known droplet Angle (contact Angle), tester, and Dyne pen? The answer is yes. The commonly used methods for judging the cleaning effect of wide-width plasma equipment and plasma cleaning machine include droplet Angle (contact Angle) method, Dyne brush method, surface energy test, etc., while other methods need some special instruments or special processing effect to react, and the scope of application is limited.   1. Droplet Angle (contact Angle) is a commonly used measurement method to evaluate the plasma cleaning effect. The test results are accurate, easy to operate, repeatable and stable. The principle of this method is to titrate a certain amount of droplet on the sample surface by optical surface contour method to detect the contact Angle of droplet. The smaller the contact Angle is, the better the cleaning effect will be. The droplet test is used to show whether the plasma has an effect on the processing of the product. In some cases, the result cannot be completely relied on to determine whether the processing requirement has been met. For example, the droplet test cannot show whether the Particle has been removed during Particle removal. Measuring different material surface contact Angle tester is a kind of wide Angle of plasma equipment before and after processing water droplets of instrument, it depends on the processed material molecules or organizational structure of different initial surface energy materials, plasma before and after processing the surface reaction is different also, so after processing point of view is different also, especially the organic material. Note: The Angle of droplet test should be unified. The size of droplet in each test should be as consistent as possible to ensure that the water used in the test does not change greatly.   2. The Dyne pen is widely used in enterprises, and its operation and detection method are also very simple. Dyne is a unit of surface tension. The method wetted and contracted the free energy of different surfaces by means of the different values of the Dyne pen, namely the liquid with different surface tension, so as to judge the level of the free energy of samples. However, due to the influence of different manufacturers producing Dyne pens, manual operation, its repeatability and stability will be slightly less. The smaller the unit dyne value of the surface energy of an object is, the lower the surface energy is. The larger the dyne value is, the greater the surface energy is, the better the adsorption property is, and the better the binding and coating effect is. The Dyne pen can directly measure the energy on the surface of an object, making it convenient and reliable to use. Note: The surface energy test fluid works in the same way as the Dyne pen.   3. SEM scanning is short for electron scanning electron microscope, which can magnify the surface of an object thousands of times, and can take microscopic images of the molecular structure.   4. infrared scanning is the use of infrared detection equipment, before and after the plasma cleaning machine treatment of the workpiece surface polarity groups and elements in the workpiece combination state detection.   Tensile (thrust) testing This method is both practical and reliable for products used for bonding.   6. High power microscope observation method is suitable for related products requiring Particle removal.   7. Slicing method is suitable for the industry of continuous slicing observation, such as PCB and FPC processing industry. By making slicing, the corrosion in the hole of circuit board can be observed and measured by crystal phase microscope.   8. Weighing method is suitable for measuring the effect of plasma on the surface of materials after corrosion and ashing. Its main purpose is to test the uniformity of wide-width plasma equipment treated by the plasma cleaning machine, which is a relatively high index.
