Single-sided to 24-layer PCB manufacturing
Manufacturer reportedGainbase lists single-sided to 24-layer PCB manufacturing in its official manufacturing documentation. Finished mechanical hole: 0.15 mm minimum. Finished laser hole: 0.10 mm minimum; separate process. Double-sided board thickness: 0.4–5.0 mm. Copper cladding: Inner 18–210 µm; outer 12–210 µm. Conventional board range. The finished mechanical-hole value is used for filtering; laser holes and HDI require separate construction review. Thickness range shown applies to double-sided boards. Which stack-up, laminate grade, finished copper and acceptance criteria will be used for this board?
