joint strength | 26 November, 2008

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 off after we snap the intended connector on. What would I expect in pull strength, tensile strength etc. What spec. would I use? Any help would be greatly appreciated.

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 withstand X-number of snaps.

Regards,

Vlad
