temp stress reliability test for SMT solder bonds

Electronics Forum | Thu Apr 09 12:25:43 EDT 1998 | Dave Hammond

I am currently involved in a reliability project related to SMT QFP and TSSOP fine pitch solder joint reliability. I have decided to use a temp chamber for stress testing. Is there a test standard that covers this? I am also a bit unsre as to whether

BGA, stress on the PCB

Electronics Forum | Fri Apr 16 08:20:58 EDT 2004 | Bob L.

We've seen problems with BGA balls breaking at in-circuit test. I did some bend testing and found that our large BGA's can handle amazing stresses at low strain rates but we get brittle fractures at high strain rates, especially with Ni/Au surface f

We conduct temperature stress test (-40 to +100C)on our products which sits on our expensive test board. This stress test on our product shorten the life span of the test board due to the extreme temperature change. I have tried epoxy coating on the

First, we know of no conformal coating that will help your situation. Second, as you say, companies recognize that stress testing of shippable products is NOT good practice, because it strips life from the product. So, your product is more expensiv
