Why should you be wary of the bristles when using an anti-static brush?
Through the actual test, it was found that most of the anti-static brushes passed the brush handle test, but the bristles were not tested.
In the national 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 to clean our circuit board, the circuit board is very easy be 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.
