Interconnect Stress Testing is a good method for testing the
reliability/integrity of the PTH and materials package.  A good overview
on the test method is at -
http://www.polarinstruments.com/support/reliability/ap301.html

Many people are performing the testing - you need to generate a specific
coupon that has a chain of the PTH size that you want to test.  Can give
you more info if you contact me directly.
