need IPC standards for lead free solder joint reliability tests | 9 December, 2004

Can anyone point me in the direction to find some IPC standards for lead free solder joint reliablity tests, such as shear tests, pull tests, vibe tests, enviroment tests, etc. I need to know what the specs. are on all aspects of reliability and how to preform these tests and what criteria is considered reliable. It's my understanding that alot of the criteria for lead free is not yet available, so even if the criteria and test to be preformed are for leaded solders it would at least be a starting point.

Thanks in advance

You're correct. There is no criteria for no-lead, but there none for SnPb, either. Solder joint strength in pull/shear will vary with lead geometry, solder volume, lead metal/metallization, the way the test is done.
