Can anybody provide information on shear testing of passive components. What standards are used etc. Thanks

solder ball shear test question

I was wondering if anyone could direct me towards documentation on shear test methods/apparatus to test the bond integrity of a solder ball to its substrate. Thanks.

I recall a couple of papers in the SMTA 'Knowledgebase' that used ball shearing and an element in a study that compared BGA [maybe uBGA] component fabrication methods, er sumpin.

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

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 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

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

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
