Manufacturing Summary
This manufacturing summary details the production of 30 8-layer FR4 panels, each 226.8 by 109 mm with a 1.0 mm thickness and custom stackup. The tighter 4/4 mil track and spacing, combined with 0.2 mm minimum holes, necessitated precise circuit imaging, etching, and plating processes to maintain feature accuracy without compromising board integrity. No impedance control was required, allowing standard signal routing within the multilayer construction.
Green soldermask with white silkscreen offered good visibility, topped by an immersion gold ENIG surface finish for superior solderability and protection against oxidation. The process flow incorporated detailed layer stack alignment and high-pressure lamination to bond the eight layers reliably, followed by solder mask application and final surface finishing steps.
Completed over 14.5 days, the run from material preparation through electrical testing confirmed all interlayer connections and overall panel performance. The resulting boards exhibited uniform quality in a panelized format, supporting consistent downstream assembly.
