Manufacturing context
HYJPCB / FineCircuit lists single-sided CEM-1 switch-controller PCB in its official manufacturing documentation. Layer construction: Single-sided. Base material: CEM-1. Copper notation: 2/0 oz. Finish options listed: OSP or lead-free HASL. Catalogue example. Heading says 2.0 mm and the detail table says 1.6 mm; thickness is therefore left unresolved. Which stack-up, laminate grade, finished copper and acceptance criteria will be used for this board?
