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

need IPC standards for lead free solder joint reliability tests

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 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

hi, I am a Hardware designer . One of my products is undergoing a Reliability test in which a resistor shows a high value on board from its specified value .However it retains the original value when its cooled under room temperature. The resistor

Insufficient solder joint

I recently encountered reflow soldering defects on a pair diode package, the smd pad had a green contamination, I'm convinced that this is not oxidation. The no-solder condition appears to be caused by a sloppy soldermask process, although over the y

We work in a "low" volume high reliability house building mixed tech double sided multi layer CCA's for long lived space applications. Our present problem is inspection questioning every dimple/anomaly on every leadless part(we put passives only thr
