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

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.

I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to whether

On 1.27mm (0.050 inches) Standard Ball Grid Array's. The ball size diameter starts at approximately 0.025 inches. If the ball size decreases to 0.012 inches (due to the solder flowing down a via) is the solder connection reliable? This is a known L

I am looking for advice or information from anyone about the possible reliability problems associated with epoxy on solder pads of discrete devices. Will the epoxy expand and lift over time, Will there be adverse reaction between the solder and the e
