Manufacturing context
Assunny Precision Circuits lists flexible PCB — published 2024 volume range in its official manufacturing documentation. FPC volume layer range: 2–8 layers, 2024 column. Production panel dimensions: 500 × 1200 mm, 2024 volume column. Minimum double-sided thickness: 0.06 mm, 2024 volume column. Inner-layer line / space: 0.03 mm; not a universal outer-layer limit. Dated 2024 volume-production column. RFPCB and small-batch ranges are separate. Ambiguously labelled copper/drill rows are excluded rather than repaired by inference. Which flex stack-up, stiffener arrangement and bend conditions are covered by the proposed manufacturing process?
