This 2-layer FR-4 board (286 × 141 mm, 1.0 mm finished thickness) was produced in a quantity of 20 pieces (5 sets) using Shengyi S1000-2M TG170 material with 1 oz / 2 oz copper. The design featured 0.3 mm minimum holes, 6 mil line width/space, ENIG surface finish (2U"), aluminum-plugged vias, and customer 1×4 panelization with V-CUT. Production was completed in 14 days with 100% flying probe testing and delivery of electrical test reports plus quality certificates.
DFM review addressed panel dimension and via plugging requirements. The panel size was confirmed at 141 × 288 mm including process edges to maintain structural integrity during V-CUT processing. Specific vias were processed with copper paste plugging while others received standard tenting per customer instructions. Silkscreen characters overlapping pads were noted with limited adjustment possible due to design constraints. Factory code and UL marking were added in the designated top layer box, with date code placed only on the bottom side to avoid interference. All marking positions and file details were verified before production release.
The completed boards met dimensional, plating, and electrical requirements with consistent via fill and clean depanelization. For detailed handling of the via copper paste plugging and panel dimension conflict in this build, refer to the related engineering case.
