Making outline
- Cut and edge-prepare unexposed copper-clad laminate witness stock, independently characterize blank geometry/material state and protect it for later coating/exposure/etch/press/drill trials
- 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
"Consumed process/reference feed, not final phone populated board or already fabricated output board required to build apparatus."
