This 8-layer board used KB-6165F TG150 material at 1.6 mm thickness with 0.5 oz inner and 1 oz outer copper. Measuring 130 × 161.6 mm, the design incorporated blind vias at 0.15 mm laser diameter, 4 mil minimum trace and space, ENIG finish, blue solder mask, and V-cut plus routing separation on a 1×2 panel. Twenty pieces were produced under a 21-day schedule after customer self-panelization.
CAM review flagged oversized solder mask openings that eliminated bridges between pads and exposed traces, via capping conflicts on double-sided open holes without tin, non-standard 0.15 mm laser vias, BGA pads requiring non-solder-mask-defined treatment to prevent cratering, and legend frames too close to pads. Additional items included V-cut copper clearance of 0.45 mm per side, process-edge test pads on all four sides, and confirmation of the KB TG150 stack-up. Openings were reduced to restore mask bridges, via plugging requirements were clarified on the production files, BGA pads were redefined, legend positions were adjusted, and V-cut test features were added to the edges.
All changes were incorporated before release. One-hundred-percent flying-probe testing was completed, and boards shipped with electrical test reports and quality certificates. The revisions addressed the blind via and solder mask constraints while preserving the specified V-cut process.
