Manufacturing Summary
This production record covered standard 4-layer FR4 PCBs measuring 160 × 95 mm with 1.6 mm finished thickness and 1 oz copper on all layers. Minimum trace width and spacing sat at 6 mil, fitting conventional geometry that permits stable etching without special controls. Lead-free HASL was applied through molten solder coating and hot air leveling, producing a uniform, solderable surface suited for mixed component assembly.
The build sequence began with engineering review and material preparation, followed by inner layer imaging, circuit imaging and etching, layer stack alignment, and high pressure lamination. Solder mask was registered and cured prior to the HASL process. Full electrical testing verified net continuity and isolation on every panel. Total manufacturing duration reached 8.4 days, allowing measured progress at each stage while preserving dimensional stability.
Completed boards exhibited consistent copper distribution, clean solder mask dams, and even HASL coating thickness. The lot met all specified tolerances without deviation, confirming repeatable execution for this standard 4-layer FR4 PCB configuration with HASL Lead Free.
