This batch consisted of 5 panels of 2-layer FR4 PCB, each measuring 137 x 115 mm with a standard thickness of 1.6 mm. Employing 1 oz copper layers and a conventional 6/6 mil track-to-spacing ratio, the fabrication followed established parameters for circuit imaging and etching. Green solder mask was applied along with white silkscreen, after which the boards received a HASL Lead Free surface finish through molten solder coating and subsequent hot air leveling. Precise drilling ensured all holes met the 0.3 mm minimum diameter requirement.
With no impedance control specified, production emphasized uniformity in plating and surface coating across the panelized format. The engineering review and material preparation stages optimized the workflow for the default stackup, enabling completion of the entire order in 1.4 days. Final electrical testing confirmed full compliance, with all panels exhibiting solid electrical performance and structural integrity.
This execution for a small-quantity standard-specification order yielded reliable PCBs that align well with typical assembly and operational demands.
