For this order of five single 2-layer FR4 PCBs, we manufactured boards with compact dimensions of 23 x 86 mm and standard 1.6 mm thickness using 1 oz copper. The 5/5 mil minimum track and spacing required precise circuit imaging and etching to achieve accurate feature definition on the narrow layout.
We applied green solder mask and white silkscreen before the HASL Lead Free surface finish. This involved molten solder coating followed by hot air leveling to create a flat, solderable surface. Comprehensive electrical testing verified that all boards met design requirements with no opens or shorts detected.
Completed efficiently in 1.7 days, the small production run allowed focused attention on each board. From engineering review through material preparation and final inspection, the process delivered consistent quality suited to the tighter geometry of these 2-layer designs.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
