Try increasing your etch -rate, this will improve your surface. Also you may want to increase your acid content in the Entek bath itself.

> Hi Techies,
> I'm currently having a problem getting even coverage on a

> solutions have been changed and different methods of precleaning have
> been tried. Short of conveyorized equipment is there anything that I
