What is a qualified anti-static brush
In the current production process of microelectronics factories, in order to clean the surrounding environment of products, anti-static brushes are usually used.
There are many types of anti-static brushes, including wide handle, short handle and toothbrush type, which are suitable for different working surfaces.
However, in the actual test, it was found that most of the anti-static brushes are tested by the handle of the brush and meet the anti-static standard, but the bristles have no anti-static effect. That is to say, ordinary soft fur.
In the national military standard, it is not clear whether the bristles need to be tested. Many manufacturers use ordinary nylon bristles. Although the brush handle is anti-static, the electrostatic voltage of the bristles during the friction test is very high, sometimes reaching tens of thousands of volts. Imagine if we use such an anti-static brush, it is difficult to clean our circuit boards. Not damaged by static electricity.
A qualified anti-static brush should not only have a qualified brush handle, but also have qualified anti-static bristles, so as to better protect our products from static electricity damage.
