We've been using SHADOW, Electrochemicals direct metalization process 
     with great success for over a year now.  I'm interested in: who else 
     is using it; what % solids the SHADOW bath itself is running at; 
     smallest hole; and aspect ratio being plated.  Our numbers are 
     3.5-4.3% solids; 10 mil holes; 7:1 hole aspect ratio.  
     
     Sometimes the SHADOW deposit builds up on the corners of the hole.  
     The small holes are very hard for the airknife to clear the Shadow out 
     of the hole.  We're tempted to push the limits of the % solids to 
     below the 3.5%.  I thought I heard some people already doing this.  
     True?  Thanks for your consideration.
