Manufacturing Summary
This 2-layer FR-4 board (570 × 20 mm, 4.0 mm finished thickness) was produced as 10 pieces using KB-6165F TG150 material with 1 oz / 3 oz copper. The long narrow aspect ratio required careful handling during processing. Key specifications included 0.5 mm minimum holes, 10 mil line width/space, lead-free HASL surface finish, and via tenting. Production was completed in 16 days with 100% flying probe testing, electrical test reports, and quality certificates delivered.
Given the 4 mm thickness and single-piece shipment requirement, production used a 10-up panel with stamp hole connections (0.8 mm holes at 0.25 mm spacing) for stability. Tooling holes (2.0 mm) and fiducials (1.0 mm) were added on process edges 5 mm from the board outline. The 0.4 mm vias specified for tenting were pre-drilled to 0.6 mm to reduce the risk of ink intrusion and solder bead entrapment in the high aspect ratio holes. NPTH hole size was confirmed at 8.05 mm with adjusted routing tolerance of ±0.1 mm. Thickness tolerance followed IPC ±10%, and production numbering was placed as requested.
All DFM clarifications were resolved before release, resulting in boards that met dimensional, plating, and electrical requirements with clean edges after depanelization. For detailed handling of the via tenting and panelization approach in this 4 mm thick build, refer to the related engineering case.
