Darren: Do you know what these residues are ? How clean is your solderbath ? How often during a day do you clean it ? My first impression is that you deal with oxides. M2C Wolfgang

Hello Mark, EPA Certification can be a tremendous help to the user that is evaluating new cleaning processes. Let�s face it, if it wasn�t for the Earth�s ozone layer, everyone would still be using CFCs and a vapor degreaser to clean stencils, PCBs

Hello I am looking for any data that confirms the long term reliabilty of no clean paste as opposed to water soluable. Does anyone have any past experiences of problems when changing over from water soluable to no clean in the SMT prcocess?? Thanks i

Same query: Do we really need to clean the board with when using RMA ? I've been told that aqeous is not needed to clean the board, what cleaner is suitable and how?

Can you recommend a good material to put in the cleaner for both water soluble AND no clean residues? Mike mweekes@phoeintl.com

Two off the top of my head are: 1 Fluxing / soldering process is either not in-control or not capable. 2 Ionic materials on the board board or components compromise the LT reliability of the product.

Continuing with Steve's comments, the true measure of whether or not residues [NC or not] are good or bad is found in the results of an laboratory analysis of the residues and an assessment of the impact of that level of residue.

An interesting explanation [from a design engineer perspective] of "skin effect" in RF circuits can be found at http://www.ednmag.com/ednmag/reg/2001/04122001/08john.htm
