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

Maybe there's no test and I don't know where or why my customer came with that requirement (I think because in one of the board shipments he got a board were a smd resistor broke, but I think that happened because miss handling), but anyway I need so

There is no test. Beyond the issues that you mentioned that affect shear, an article published in a recent [1/01] "Journal Of Surface Mount Technology" documents that shear is also dependent on the rate of shear. You may be able to contact the auth

Hi, I need support on the method or applicable standard to measure the shear force strength on chip capacitors and resistors. I know the soldered joints strength is related to land desing, solder volume, pcb and component solderability, component

Sure, researchers measure shear as an element of their material characterization process, but that does not make it an acceptance test. [Truly, this conversation is not uncommon on SMTnet. So, it would not surprise me if an enterprising something o

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

Scott: Sounds like fun: � Solder joint strength in pull/shear varies with lead geometry, solder volume, lead metal/metallization, and the test method. � Among things, IPC-TM-650 talks to getting pads off-of boards. For instance: Method 2.4.8 is for

There is no standard. This is a relative test. If you wish to do tests of this kind, we suggest to pay attention to the following points: * Shear strength of soft solder depends on the deformation speed applied. The faster the material is deformed t

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
