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

Prepare separately identified NMP and isopropanol stocks as a laboratory solvent assortment
Keep separated intermediate states and retain/assay a witness sample; process settings and acceptance limits remain unknown.

What remains unresolved

Making route and target-level requirements not researched.
Complete inventory, source-supported recipe, independent acceptance, caller demands, stock/loss and availability remain unreviewed.
This is an assortment, never one blended solvent; other consumer-specific solvents (OLED synthesis/resist/epoxy) remain separate explicit frontiers. Generic callers need exact selection.

Unselected discovery proposals

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