Manufacturing Summary
These 15 units of 2-layer FR4 PCB measured 99.04 × 75.87 mm with a 1.6 mm thickness and 1 oz copper weight. The design used a conventional 6/6 mil trace and spacing geometry together with 0.3 mm minimum holes, requiring no special geometry controls. A custom stackup was built to exact specification, then coated with matte black solder mask and white silkscreen before receiving lead-free HASL surface finish. This surface combination demanded careful mask curing and solder leveling to ensure even coverage and reliable pad definition across the limited batch.
After engineering review and PCB material preparation, circuit imaging and etching defined the traces on both layers. Solder mask was applied and cured to produce the specified matte finish, followed by molten solder coating and hot air leveling to form a uniform, lead-free HASL surface. Every board completed full electrical testing to confirm net continuity and isolation.
The complete run finished in 5.3 days and delivered consistent thickness, hole quality, and surface appearance throughout the set. The executed process confirms dependable results for small-quantity 2-layer FR4 PCBs finished with matte black solder mask and HASL Lead Free.
