Manufacturing context
Hopesearch PCB lists multilayer PCB — volume-production range in its official manufacturing documentation. Production layers: 2–16 layers. Production thickness: 0.5–3.2 mm. Sample-only ceiling: 22 layers; outside production filter. Base copper: 1/3–6 oz, as listed in the process table. Volume layer and thickness values from the published 2026 table. Base-copper weight is not a finished-copper guarantee. Hole and routing limits need to be confirmed for the chosen copper and construction. Which stack-up, laminate grade, finished copper and acceptance criteria will be used for this board?
