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
- Form a fine-pitch laminate package carrier with copper interconnects and finish; chipset-specific package grade remains unknown
- 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
- Discovery hypothesis only: quantitative demands, full recipe, quantities, losses, compatibility and acceptance remain to be researched.
