[SI-LIST] Re: Solder migration during RFIC testing

Hi, Arvin.

I prefer to use IC holder for early characterization which is able to contact 
with PCB pattern directly.
The IC holder is very helpful to evaluate small number of sample in bench test.
This is consist of just one long female screw to press down chip on PCB pattern 
and, 
                        one square cover having four thru holes and one screwed 
hole and,
                        four legs to keep tight the cover on the PCB and,
                        four holes on the PCB (you can use the thru holes of 
socket in many cases) 

This can guarantee less inductive component. So the repeatability and 
reliability of measurement would be increased. 
But as you can understand,it is not good to be used for testing in large number 
of samples.

Bye.
