Charles Barker@IO-US 11/04/97 10:11 AM Graham, We are using water soluble spacers from BIVAR. I believe they are available in different thicknesses. Regards, Charlie B.

In wavesolder attachment of some through hole components, we have to provide a temporary standoff to keep the part off the board surface. Currently we are doing this with bits of wire or other mechanical means, which are then removed after wavesolder. Some components we keep off the board with a washable solder masking material, but this is not a precise or quick method. Is there such a thing as a preformed standoff that will dissolve when the assembly is washed, that would be put on the lead before insertion into the board? Thanks!
