Mark: For our small depanelized PCA's we place them in an open top wire mesh basket. Then an expanded mesh(diamond pattern), notice that I did say wire mesh, piece of sheet stock cut slightly under size of the basket dimensions is placed over the top of the boards. The expanded mesh openings are @ 25-50% smaller than the smallest PCA. This allows for ample water flow to the parts for washing and rinsing but is heavy enough to prevent them from jumping around in the spray rinse and drying sections. If you are going for cheap you can use aluminum as long as it is compatible with your wash chemistry if not go with SS. You may want to try a couple of different material thickness' to make sure there is enough weight for your application. Either way it is fairly inexpensive and should last a long time. It is simple and does not require a lot of hardware and fooling around. Regards Michael Barmuta Staff Engineer Fluke Corp.

They are in baskets, the thinnest (so I'm told) available. Perhaps some kind of mat or other mesh inside the basket? Has to be inexpensive.

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?
