Don't throw away your probe tip accessories?
Cheers

I have been thinking if it may be possible to make a probe tip where
only a part of the circumference is conductive. You might need to
rotate the probe to reach the pin you want, but I don't think that
would be a big problem.
I found one hobby project where a probe tip was made from a piece of
single sided PCB. But copper tarnishes quickly, and glass fibers are
very abrasive.
I have not been able to figure out a way to fabricate a useful
prototype.

Yes, I do use sewing needles jammed into a large micro grabber.
And I have a set of micro grabbers that work great on soic size
packages. Still looking g for a good octopus for holding
everything in place.
And I still have my probe accessory bag.
In addition I usually add some 030 holes as test points to the
layout to make troubleshooting easier.
