This 8-layer FR-4 board (77.5 × 60 mm, 1.6 mm finished thickness) was built as 10 pieces using Shengyi S1000-2M TG170 material with 0.5 oz copper on inner layers and 1 oz on outer layers. The design featured 0.1 mm minimum holes, 5 mil line width/space, ENIG surface finish, blind and buried vias, and aluminum-plugged vias. Production used AIVON panelization with 4 mm process edges on left and right sides, completed in 9 days with 100% flying probe testing and full electrical test reports plus quality certificates.
DFM review resolved several layer and plating conflicts. Copper weight specifications were clarified and aligned between the order requirements and stack-up, with adjustments made to ensure proper plating on buried vias (L2-L7). Solder mask openings versus tenting were verified for critical vias and etched frames. Legend (silk screen) requirements were confirmed as none, with UL marking and other identifiers added on the bottom side per reference. Stack-up was optimized and confirmed to meet the target 1.6 mm finished thickness while supporting reliable via formation and aluminum plugging.
All production files and parameters were confirmed before release. The completed boards met dimensional, electrical, and via reliability requirements with consistent plating and surface finish.
