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

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

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

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

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

RPS (Robtic Process Systems - I think) Makes a system called a Wet Balance tester. This machine is useful for Solderability on PCB sections and Components. Also for more info please go to http://www.empf.org/html/empfset.htm and down load Decemeber

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

First, any results of pull or shear tests are unscientific at best. [We pop our BGA from boards with, appropriately enough, a beverage can opener.] Second, we have no have problems with your ENIG specification. Third, as with your customer, we'd e
