Manufacturing Summary
This 18-layer HDI panel PCB order required a custom stackup to accommodate its 3-step blind via structure, 3/3 mil minimum trace and spacing, and 0.1 mm holes. Produced in a quantity of five boards measuring 124 × 202 mm with 2 mm finished thickness and 1 oz copper, the design demanded exact layer registration and sequential lamination to maintain signal integrity across the impedance controlled layers.
We performed laser microvia drilling, via filling and plating, followed by matte black solder mask and immersion gold ENIG surface finish. Trace width compensation was applied during inner layer imaging and etching to achieve the tight geometries. TDR impedance testing at multiple points confirmed that the finished panels met the specified tolerances, while full electrical testing verified net continuity and isolation.
The 16-day production window allowed thorough verification at each sequential lamination stage, resulting in consistent electrical performance and dimensional stability across all delivered panels. The completed impedance controlled HDI PCBs reflect the process controls required for this advanced multilayer configuration.
