I thought there was a link for test labs somewhere on the site, but didn't see it in a quick look. Here are some I know of that should be able to run the test: Trace labs ACI Technologies (American Competitive Institute) STI Electronics

What do you mean by "But after performing temperature cycle test, the former aging rate (from the shear strength ) seems faster than the latter."? Comments are: I can't recall having heard the term "precipitation hardness" [not that that means anyt

There's no such specification. Not should there be. Shear tests [in our opinion] are senseless, because: * Solder joint strength in pull/shear varies with lead geometry, solder volume, lead metal/metallization, and the way the test is done. * She

Can anyone point me in the direction to find some IPC standards for lead free solder joint reliablity tests, such as shear tests, pull tests, vibe tests, enviroment tests, etc. I need to know what the specs. are on all aspects of reliability and how

I'm trying to replace the PTH connectors with the SMT connectors in my design, and would like to make sure the SMT connector solder joints are as stong as PTH's. What's the right test to verify that? Is Pull and Shear test is the right choice? Where

I do not doubt about the power of the 552 and 580, but in some cases it may be overdone. For just a simple (straight forward) shear test, you can also look at: http://www.chatillon.com/products/dpp.html (�Low Capacity Mechanical Force Gauge. These er

O' Connor Haaa. It's usually the design guys that foist the problems onto my desk. Now that is one shrewd process type that you have working at your company!!!! Can I have his / her name and number to get some tips on the technique that he / she

In a previous job, we had torque off requirements for different sized components for our screen print adhesive (non-conductive in our case). We used a torque watch that would measure max torque, so we could test production boards, shear testing was

Hi Rajeshmara, Mail sent with the datasheet of the glue we use in production. Thanks for first information you provide me for the shear specifications on 1206. But can you be more precise on this point ? How did you define it ? Is anyone have more

Continuing, I�ve optioned about the uselessness of shear testing of solder connections on this forum previously. So, the points that you make about the elusiveness of developing a standard for measuring solder connection strength is well taken. I�l
