For this order, we manufactured 10 units of 2-layer FR4 PCBs measuring 74.91 x 39.85 mm. The boards were built to a standard 1.6 mm thickness with 1 oz copper foil, conventional 6/6 mil trace width and spacing, and drilled holes no smaller than 0.3 mm. Following engineering review and material preparation, the circuit patterns were imaged and etched with attention to maintaining uniform conductor profiles.
Subsequent steps included solder mask application in green, white silkscreen legend printing, and HASL Lead Free surface finishing using molten solder coating and hot air leveling. This combination delivers cost-effective protection and reliable soldering points for standard applications. Since impedance control was not required, processing parameters remained at default settings throughout.
All boards underwent comprehensive electrical testing to confirm performance before shipment. The complete manufacturing cycle took 5.2 days, yielding consistent results that meet the specified requirements for this straightforward FR4 design.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
