Waveform contact retained-force comparison fixture
Separate known-weight/lever direct compression geometry applies independently referenced force to contact retention/deflection specimens and observes actual retained force/geometry under thermal conditions. Does not infer contact pressure from screwdriver torque. Hardware, range, uncertainty and first acceptance remain open.

Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline
- Build supported known-weight lever and independently measured direct compression/contact-deflection geometry, then compare actual retained contact force and thermally repeated deflection without equating screw torque to preload
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Torque-calibration-fixture realizes torque, joint-pull-test-fixture tensile/peel load and lead-integral-current-flex-fixture electrical/flex duty. None automatically measures retained small electrical-contact compressive preload. Actual earlier lever/hanger/reference constituents reused; no electronic load cell or finished harness under test supplies the reference."
