2 Layer FR4 PCB Production Record #FR4-20260930-083

For this order of five 2-layer FR4 PCBs, we processed boards measuring 86.99 × 121.92 mm with a standard 1.6 mm thickness, 1 oz copper, 0.4 mm minimum hole size, and 6/6 mil trace spacing. The black soldermask paired with yellow silkscreen created a high-contrast finish that required precise mask alignment and legend curing parameters to maintain edge definition and color consistency across the small batch.

Production followed a controlled sequence of engineering review, material preparation, circuit imaging and etching, solder mask application, then molten solder coating and hot air leveling to achieve a uniform HASL Lead Free surface. This finish ensures reliable wetting for both through-hole and surface-mount assembly while meeting RoHS requirements. Final electrical testing verified continuity and isolation on all five boards, confirming the circuits performed to specification.

Completed in 1.6 days, the run delivered five consistent 2-layer FR4 PCBs with the requested yellow-on-black appearance and solid solderability. The straightforward parameters combined with the non-standard color choice were executed without deviation, providing dependable boards ready for immediate integration.
