Hi Nick:

Hans' explanation to this topic is excellent.  I couldn't add anything but
would like to bring to your notice that Karl H. Dietz in his CircuiTree
Column "Tech Talk - Fine Lines in High yield (Part XLVIII): Quick Turn Shops
(August 1999)" and "(Part XXXVIII): Tent and Etch (Part 1) (October 1998)"
give panel and pattern plating processes some in-depth analyses.  These are
very good articles.

baord on
plating.
One is PTH than Panel plating and then pattern plating.
