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

Cast selected polyamic precursor, remove solvent and thermally imidize the film
Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.

What remains unresolved

Candidate method, complete inventory, caller demands and physical compatibility require research and review.
Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
Thermal cycle/film stress/pinholes and flexible-laminate dielectric/interface requirements unknown.
