Manufacturing Summary
This production record covers a standard 4-layer FR4 PCB order with 1.6 mm finished thickness and 1 oz copper weight across all layers. Engineering review and material preparation confirmed the core and prepreg materials matched the required stack-up before inner layer imaging defined the internal circuitry at conventional 6 mil trace and spacing. Etching produced clean features, after which precise layer stack alignment and high pressure lamination bonded the four layers into a stable panel with accurate registration.
Drilling and plating were followed by solder mask application and surface finishing through molten solder coating and hot air leveling, yielding a uniform HASL Lead Free coating. The process concluded with full electrical testing that verified net continuity and isolation across every board. Completed in three days, the run delivered consistent thickness, hole wall quality, and solderability without deviation from specified parameters.
Boards from this sequence demonstrate reliable execution for standard multilayer designs, providing customers with finished product that meets both dimensional and functional expectations for assembly and long-term operation.
