KP Chan,


In the past we have had a problem with solder blow-out on .093 and 
thicker material evan with
sufficient copper thickness. It turned out to be excess moisture in the 
substrait causing the 
blow-outs and baking them in a 200F oven for about ten min. takes care 
of the problem.

                         Hope this helps
                              Lee
