2 Layer FR4 PCB Production Record #FR4-20261023-030

For this order, ten 2-layer FR4 circuit boards were produced, each measuring 36 x 36 mm with 1.6 mm thickness and 2 oz copper weight. These single PCBs featured a distinctive red solder mask with white silkscreen printing and were finished with HASL using lead for optimal solder wetting. The minimum 6 mil trace and spacing along with 0.3 mm holes represented conventional geometry, allowing standard processing methods to be effectively applied despite the heavier copper.

Manufacturing began with engineering review and material preparation, followed by circuit imaging, thick copper electroplating, and controlled etching to accurately define the traces without compromising the design tolerances. Solder mask was then applied, after which molten solder coating and hot air leveling created the final surface. This sequence ensured good copper adhesion and a flat, solderable finish suitable for manual or automated PCB assembly.

The entire manufacturing process took 1.3 days to complete. Electrical testing verified functionality across all boards, resulting in a set of reliable PCBs that accurately reflect the specified 2 oz copper construction, red solder mask, and leaded HASL requirements. The small batch size permitted close monitoring at each stage for consistent quality.
