Anyone know any international standard (e.g. IPC, JIS) for the SAC lead free solder strength ? If no, any industrial / company standard for it ? Besides, any mathematical model which can help to calculate it.... express in "Force / area "

Just as you will not find such a specification for SnPb solder, you will not find such a standard for SAC. We talked about solder strength several times previously here on SMTnet. Search the fine Archives for others comments. For instance: http://

How to test the reflow solder joint shear strength? What are the specification to test solder joint shear strength? What are the different methods to test the solder joint shear strength? Vijayashree

Shear tests are [in my opinion] senseless. The shear stress you measure depends more on the shear rate and on the point where the force is applied than on the grain structure. When shearing a component, you not only apply shear stress, but also roll

Hello everyone, after a short layoff I am glad to be back. I have a question. I have a button (snap button) that is being soldered to a strip of sac coated copper. We are questioning the joint strength of this from our vendor as we see these popping

I don't think you can find any specs on that. As long as a solder joint can not be broken by virtually "blowing over it" any reading on the UTS, or shear strength can be very confusing. You can specify, though that the assembly (joint) should withsta

Hi davef, Appreciate your advise......

Davef That's why I mentioned that this was the "Closest" written procedure I've found related to this type of tests.

If there's no shear strength standard for solder joint, how will I define my pad width and length then. I have a 8.5 mils width and my component lead width is 8.66 mils based on manufacturer's minimum width specification. How will I identify that it

we also have a need to measure the solder bond strength of our gull wing parts on our pwb. there are many published comparisons between eutectic SnPb and no Pb solders out there. the number that comes to mind is about 10N to 15N. I have not looked
