Manufacturing Summary
The production record for this High-Density Interconnect PCB order covered 30 panels built to 6 layers with blind vias in a 1+n+1 configuration. At 0.8 mm finished thickness and with overall panel dimensions of 23.7 by 14.4 mm, the design incorporated 4/4 mil minimum track and spacing as well as 0.1 mm laser-drilled holes. These parameters required sequential lamination after the initial laser microvia drilling and plating steps.
We prepared the materials and performed precise layer stack alignment prior to high-pressure lamination to maintain the tight registration needed for this geometry. Following circuit formation, black soldermask and white legend were applied before the electroless nickel and immersion gold deposition. Electrical testing at the end confirmed that all 30 panels met the design criteria for continuity and isolation.
The complete manufacturing cycle took 17.4 days from initial engineering review through final inspection. This execution highlights the process controls applied to produce consistent HDI PCBs with ENIG finish for reliable downstream assembly.
