That sounds interesting. I have used regular tweezers to slip sm caps
into a fixture I made. This goes pretty fast except when I accidentally
twang a part into some far and unknown location.

Did you make these youself? Can you give a quick description.

I can think how I could make low capacitance tweezers, but not how to
flexibly connect them to a capacitance meter and get consistant
readings.
Wayne Kerr used to make a VHF admittance bridge which serves well for
measuring chips, and they can be bought for less than £100 (813? bridge)
in UK
leaded low value ceramic and silvered mica have their Tc and loss
modified by the effect of the encapsulation material.
It therefore follows that chips npo chip will be better.
