Embodiment Construction
[0024] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation methods provided according to the present invention are described in detail as follows:
[0025] Down:
[0026] see figure 1 , a method of using laser particle counters to indirectly test the dust generation of dust-free products; the method uses laser particle counters to test the number of particles in the liquid before and after cleaning the dust-free products, and obtains the dust generation of dust-free products. By comparison For products from different suppliers, use dust-free products with a relatively small amount of dust generation; (take anti-static finger cots as an example) The specific implementation steps include:
[0027] 1. Select the experimental equipment:
[0028] (1) Laser particle counter: used to test the number of pure water particles;
[0029] (2) Beaker: a container for pure water;
[0030] (3) Ultrasonic generator: an instrument used ...

The invention discloses a method for indirectly testing the fume amount of a dust-free appliance by adopting a laser particle counter. The fume amount of the dust-free appliance is obtained through testing the particle amount in pure water before and after the dust-free appliance is washed by the laser particle counter and the dust-free appliance with relatively less fume amount is selected through comparing the products of different suppliers. The method comprises the following implementation steps of: (1) taking more than two clean beakers and respectively adding filtered pure water with equivalent amount; (2) testing the particle number of the pure water 3-5 times for averaging; (3) placing a sample into the pure water subjected to the test, placing the two beakers into an ultrasonic generator, and carrying out ultrasound for same time at same frequency; (4) taking out the samples in the beakers after the ultrasound; (5) testing the particle number of solutions in the beakers by using the laser particle counter; and (6) carrying out qualitative selection on the particle number in the tested samples obtained. The method is simple and fast and has an extremely obvious effect.
Description
technical field [0001] The invention relates to a method for testing the dust generation of dust-free products, in particular to a method for indirectly testing the dust generation of dust-free products by using a laser particle counter. Background technique [0002] With the improvement of manufacturing technology, electronic products are gradually developing towards fineness and miniaturization. More and more products are produced in the clean room. Dust-free supplies are also an important part of production management. [0003] When choosing to purchase dust-free products, due to the lack of simple and practical equipment, it is impossible to conduct daily comparison tests on the dust generation of dust-free products. At present, the Hank roller equipment used to test the dust generation of dust-free products is large in size, high in cost, inconvenient to operate, and takes a long time to test. [0004] Therefore, it is one of the urgent problems to be solved by those ...
