Manufacturing Summary
This 6-layer FR-4 board (74.62 × 84.53 mm, 1.6 mm finished thickness) was produced as 5 pieces using KB-6165F TG150 material with 2 oz copper on both inner and outer layers. The design featured 0.25 mm minimum holes, 6 mil line width/space, ENIG surface finish, via tenting, and AIVON panelization with 4 mm process edges on top and bottom. Production was completed in 14 days with 100% flying probe testing and delivery of electrical test reports plus quality certificates.
DFM review identified several manufacturability concerns. Tight board edge clearances risked exposed copper after routing and were adjusted per customer feedback. Multiple vias positioned directly on pads required clarification to avoid incomplete pads after aluminum plugging. Silkscreen characters overlapping pads were flagged for potential soldering issues. Hole attributes were confirmed for several NPTH locations where drill size matched pads with no connecting traces, and PTH designations were updated on larger holes. Stack-up was aligned with customer-provided structure and available material. Final panelization and production files were verified before release.
The boards were delivered meeting all dimensional, plating, and electrical requirements with clean edges and reliable via coverage. For detailed resolution of the edge clearance and hole attribute conflicts in this 2 oz copper build, refer to the related engineering case.
