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.
