Chris,

We use very inexpensive metal-handled acid brushes with bristles cut down to
approx. 3/8 inch.  We have been using them for years.  Nearly any production
tool supply house has them.

Dear All,

we currently use static dissipative brushes for cleaning wasted chips
off our placement machine feeder bases, and we also use them with a
solvent for cleaning localised areas of boards when rework has been
carried out.

The problem is that they are very expensive, so does anyone know of any
sources of reasonably inexpensive brushes?

I have seen other companies use wooden handled paint brushes with the
bristles cut down for these purposes - I assume this is not a good thing
due to the bristles not being ESD safe ?

Thanks in advance for any replies.
