We produced five individual 2-layer FR4 PCBs measuring 280 × 480 mm with standard 1.6 mm thickness and 1 oz copper. These single boards followed conventional 6/6 mil track and spacing with 0.3 mm minimum holes, green solder mask, white silkscreen, and HASL Lead Free finish. No blind vias or impedance control were required, allowing straightforward processing of the large-format panels while maintaining flatness throughout fabrication.
The sequence began with engineering review and material preparation, followed by circuit imaging and etching to define the conductors. Solder mask application preceded molten solder coating and hot air leveling to create an even HASL Lead Free surface finish. Every board then completed full electrical testing, confirming continuity and isolation within the expected parameters for this specification.
Production finished in 1.3 days, delivering consistent thickness control and solderability suited to the customer’s low-volume requirement. The executed process delivered reliable 2-layer FR4 PCBs that meet standard industry demands for this board size and geometry.
2 layer FR4 PCBs deliver cost-effective solutions for most electronic designs. Their simple structure enables consistent quality and efficient production cycles.
