How ceramic backed precision thin film resistor networks are constructed and laser trimmed.
Examples come from the resistor networks in the 7.5 digit Keithley DMM7510 Multimeter, manufactured by Fluke.

Dave demonstrates why gold plated multimeter probes matter, and why you should be using them for all your electronics measurements.
NOTE: Many people didn't understand the point of this video. It's about oxidisation of contacts, gold basically doesn't do this, other probes can.
Also gold probes are not necessarily recommended for regular high current, high power electrical use, that's what I mean by an "electronics use", as opposed to "electrical" use which is why Fluke for example don't offer gold plated leads.
And as always, YMMV.
Fluke offer fine top "electronics" gold probes: http://amzn.to/2fCuoSN

A teardown of the front end PCB in the HP 35660A Dynamic Signal Analyser.
Dave does some preliminary investigation to see what opamps and FET's are unsed in the analog front end to see if they can be upgraded for better performance.
This is more for Dave's record than interesting info.
