I think that creating a new IPC standard dealing just with potting and 
encapsulation is a good idea idea and would be willing to be member of the 
Task group developing it.  We can probably start with some of the documents 
NASA publishes on this.  I also recommend we include varnish coating and/or 
potting of magnetic components as part of this.

I see no benefit of creating a component cleaning document; most folks do 
not clean parts after receipt inspection.  They just assemble them on 
boards.  Whatever cleaning is done is done by the part manufacturers and IPC 
has no control over how they clean the parts they manufacture.
