We manufactured five single 2-layer FR4 PCBs measuring 17 x 32 mm at 1.6 mm thickness with 1 oz copper. The 5/5 mil track and spacing required precise circuit imaging and etching to maintain clean definition and registration across the compact boards. Material preparation and engineering review were completed with attention to the small lot size and feature tolerance, while default stackup kept the process aligned with standard FR4 construction.
Green solder mask and white silkscreen were applied uniformly before lead-free HASL surface finish. Molten solder coating followed by hot air leveling produced a consistent, solderable surface without introducing thermal distortion on the thin panels. With impedance control not specified, the sequence focused on straightforward execution that still respected the tighter geometry constraints.
Electrical testing confirmed continuity and isolation on every board. The entire run was completed in 1.7 days, delivering five functional boards that met all dimensional and electrical criteria for this small-quantity order.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
