They are therefore unsuitable for cleaning ESD sensitive assemblies. Nonetheless it is necessary to remove solder flux and other dirt particularly in SMD assembly where there are high densities of components. A range of conductive brushes allows thorough cleaning without the risk of generating static charges. Description: The brushes consist of a conductive plastic handle and Thunderon conductive fibres, mixed with animal hair if stiffness is desired. Resistance from the tip of the brush to the handle is less than 5 x 106 ohm. Brushes should be used by operators who are earthed so as to dissipate any triboelectrical charges. Hard brushes are for scrubbing whilst soft ones are for brushing of delicate items such as optics and diskettes. The brushes may also be used by an earthed operator to remove a surface charge on a nonconductor by slowly moving the brush across the surface about 2 - 5 mm above it.
