[Premium-Rx] Removing SMT Components

[Ed Tanton]

To make (relatively) easy value measurements of SMT parts, you need to get 
a kind of probe that is similar to a Kelvin probe-that is to say: like a 
pair of tweezers. You simply pick up the component using these, and read 
your value. Usually, these probes are terminated in a BNC connector, so you 
will also need-in that case-a dual (male) banana-to-BNC (female) adapter. 
One of mine was made by ITT-Pomona, has no number on the package, but is 
labelled: "Test Tweezers".

NOTE: If you plan to use this setup with an AADE L-C Meter, be aware that 
the hole separation in the AADE unit is NOT standard, so you have to take a 
pair of short (male) banana cables with large alligator clips on the ends, 
and connect those to the male parts of the BNC-to-banana adapter.

Besides the expense all of this entails, you should also know that the 
parts tend to pop out of the tweezers a lot, making the whole thing 
questionable as a proposition-especially considering previously raised 
reliability issues.
