That didn't look like anything special. The gold-sputtered
mylar just has to be flat.
Watch this Soyuz video around the 1:50 mark:

The mylar is put into the tensioning ring, and tensioned by the
technician by hand. He doesn't measure the tension with any device!
Also, the technician securing the diaphragm to the backing plate,
does NOT appear to use a torque-wrench!
I'm not claiming the technicians don't need skill to do this work,
but it's clear there aren't any secrets in capsule building.
I would say reverse-engineering is the bane of all Mic-Snobs!
