4 Layer Rogers PCB Production Record #ROG-20230422-0073

This order involved the production of 50 pieces of 4-layer Rogers RO4003C PCBs, each measuring 38 x 38 mm and built to a 1.6 mm thickness using 1 oz copper layers. The design called for a standard 6/6 mil minimum track and spacing with holes no smaller than 0.3 mm. We applied a green solder mask and white silkscreen over the specified bare copper finish. Special care was taken during Rogers material preparation and low loss material lamination to preserve the substrate's dielectric performance throughout the high-pressure lamination stage.

The absence of blind vias allowed for a straightforward layer stack alignment and circuit imaging and etching process. Following solder mask application, all boards were subjected to comprehensive electrical testing to confirm continuity and isolation. The compact board size combined with the production quantity of 50 enabled efficient processing while maintaining control over registration and etching uniformity.

Completed within a 10-day production window, this run delivered consistent boards suited for high-frequency applications. Every step from the initial engineering review through to final testing supported the reliability required for this Rogers PCB with bare copper surface.
