I need to amend this and stated that I made a typo in the title and in fact
meant dry-film, not LPI.
Thanks,

Subject: [TN] Info on LPI tenting of vias, both sides
Hello everyone,
I am looking for information on the potential pitfalls of using LPI via
tenting on both sides, leaving an air pocket in the vias. Application is
NOT Pb-Free.
I located this article description, and wanted to see if anyone had it, but
other information, inputs, or articles are also welcome:
Title: An Evaluation of Via Hole Tenting with Solder Mask Designed to Pass
MIL-P-55110D Thermal Shock Requirements
Author(s): J.J. Davignon, F. Gray
Journal: <http://www.emeraldinsight.com/0305-6120.htm> Circuit World
Thanks!
