Manufacturing Summary
This 2-layer FR-4 board (179 × 158.3 mm, 1.6 mm finished thickness) was produced in a quantity of 120 pieces (20 sets) on KB-6165F TG150 material with 1 oz copper on both sides. The design featured 0.3 mm minimum holes, 3 mil line width/space, ENIG surface finish, full solder mask over vias, and 3×2 panelization with 7 mm process edges on all four sides using V-CUT depanelization. Production was completed in 11 days with 100% flying probe testing and delivery of electrical test reports plus quality certificates.
DFM review focused on panelization and manufacturability. Component pads positioned too close to or over the board edge were adjusted per customer panel design recommendation to maintain 7 mm borders and prevent exposed copper. Tight 4 mil pad spacing was highlighted as insufficient for reliable solder mask bridges; customer confirmation was obtained on acceptable minimums. PTH holes without solder mask openings risked ink flow onto pads affecting component insertion, while mixed via windowing (some double-sided open) required clarification to avoid ink intrusion and edge redness. Silk screen frames, character placement near pads, and process edge details including fiducials, V-CUT lines, and copper balancing were all verified and optimized in the final production files.
All confirmed adjustments were implemented, resulting in boards that met dimensional tolerances, solder mask coverage, and electrical requirements with clean V-CUT edges. For detailed resolution of the tight pad spacing and edge clearance along with V-CUT panelization handling in this build, refer to the related engineering case.
