Manufacturing context
Honglian Circuits lists six-layer optical-module PCB — catalogue example in its official manufacturing documentation. Laminate: Panasonic R-5775G, identified as M6 on source. Layer count: 6. Finish: ENEPIG. Special construction: Resin-filled and capped vias; impedance-controlled design. Specific optical-module product example from the official catalogue. Its line/space figures are not advertised as factory-wide limits. The 0.5 mm drilling figure is not a finished-hole guarantee. Which stack-up, laminate grade, finished copper and acceptance criteria will be used for this board?
