2 Layer FR4 PCB Production Record #FR4-20260814-012

This order involved manufacturing 20 pieces of 2-layer FR4 boards in a compact 40 x 55 mm footprint. With a standard 1.6 mm thickness, 1 oz copper, and 6/6 mil minimum track and spacing, the design aligned with conventional fabrication guidelines. Our engineering team reviewed the files before proceeding with material preparation and precise circuit imaging to ensure accurate pattern transfer on these smaller boards.

The combination of matte black soldermask and white silkscreen presented a visually distinct requirement. We applied the solder mask carefully to maintain consistent texture and coverage, followed by molten solder coating and hot air leveling to achieve the HASL with Lead surface finish. This finish supports robust soldering performance in subsequent assembly stages.

Following completion of all layers, we conducted full electrical testing on each board. The production cycle wrapped up successfully in 4.5 days, yielding a reliable set of PCBs that met all specified tolerances and quality criteria.

This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
