This order consisted of 10 pieces of 2-layer FR4 PCBs, each measuring 172 × 80 mm with a standard 1.6 mm thickness and 1 oz copper weight. The design used conventional 6/6 mil trace width and spacing together with 0.3 mm minimum holes, making it a straightforward yet precise build. A matte black soldermask paired with white silkscreen was applied, requiring careful exposure and development parameters to achieve uniform coverage and sharp legend contrast without compromising adhesion.
After engineering review and material preparation, the team performed circuit imaging and etching on the double-sided cores, followed by solder mask application. The boards then received molten solder coating and hot air leveling to produce a reliable HASL with Lead finish. Every board underwent full electrical testing to verify net continuity and isolation, confirming consistent quality across the entire small batch.
The complete run was finished in 1.8 days, delivering boards that met all dimensional and electrical requirements for straightforward assembly and long-term reliability.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
