Mark,

        We used a large stainless steel basket from EMC.  (20" x 20" x 2")
There are several others available.

        As the mesh was large (about .5" x .5") we lined it with stainless
screen.  The lining was not stretched tight, to provide some protection for
the small assemblies.

We were using a Hollis Hurricane aqueous cleaner with 10 hp wash/rinse
pumps.  Even with the small mesh screen we were able to adequately clean the
boards.

Hope that helps.

Rich

        Subject:  [TN] Small PCBs in wash

        We're experiencing some damage to some small PCB's (0.75"x1.75")
that occurs during their trip through the aqueous cleaner.  The boards are
originally processed in a panel but some require rework or additional
processing once they have been depanelized.

        Can anyone suggest a method to secure these small boards inside the
wash racks as to prevent this damage?

        Mark Charlton
