Beware of using anti-static brushes
Through the actual test, it is found that most of the anti-static brushes pass the brush handle test, but the bristles have not been tested.
In the national military standard, it is not clearly stated whether the bristles need to be tested. Many manufacturers use ordinary nylon bristles. Although the brush handle is anti-static, the static voltage of the bristles during the friction test is very high, and can sometimes reach tens of thousands of volts. Imagine if we use such anti-static brushes, it is difficult to guarantee the cleaning of our circuit boards No damage from static electricity.
A qualified anti-static brush, not only must have a qualified brush handle, but also qualified anti-static bristles, so as to better protect our products from electrostatic damage.
