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

Assemble a linear resonant haptic actuator hypothesis; moving mass, spring, magnet and coil must satisfy future stroke and fatigue requirements
Develop a bounded process specification and establish earlier availability of every listed physical prerequisite.
Make trial pieces, measure interfaces and performance with independently established references, and reject incompatible outputs.

What remains unresolved

Making route and target-level requirements not researched.
Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
Selected wirebond package hypothesis does not establish flagship I/O density, power delivery, size or thermal capability; flip-chip bump/underfill architecture is a separate OR alternative requiring its own complete inventory.

Unselected discovery proposals

These are research questions, not published manufacturing dependencies. The seed combines alternatives, operating requirements and verification relationships.
