This is one for the board fabricators.

We are currently meeting an Ionic Cleanliness spec for 1 of our customers
set at 0.5 ug/Sq Cm on the finished cards. We are acheiving this using an
extra cleaning step. This is largely manual an fairly time consuming. We've
experimented with using dishwashers and although this has helped with
respect to labor intensity, it hasn't done much to improve cycle time.

Anybody had any experience utilizing conveyorized equipment or putting
improved cleaning in-line with existing processes (both HASL and Immersion
White Tin)?
