[SI-LIST] Re: Rigid-Flex Testing

Tom, 

I don't know what your application looks like, but if you can hook up a TDR
somehow you could measure the distance to the reflection.  Do you have
access to an X-Ray machine in your lab?  This might be another method since
it works on bones (though you might not have good enough resolution
depending on the size of your flex).

Unlike all the accomplished works on EMI, I don't have any scientific
evidence, don't have any papers, didn't write any books, nor do I have any
links to websites for the next method <grin>, but you can always try firing
the thing up and bend the cable back and forth to see if you get an open.  

...just giving the mouse some exercise...

Does anyone have a good method for detecting partial breaks in a trace in
the flex portion of a rigid-flex PCB?
