The manufacturing of these 15 standard 4-layer FR4 PCBs proceeded smoothly from the initial engineering review. Each board measures 30.28 x 56.4 mm with 1.6 mm thickness and 1 oz copper layers. The 10/10 mil minimum track and spacing along with 0.4 mm holes represent conventional geometry, supporting efficient production without special constraints. Material preparation and inner layer imaging established a solid foundation for the multilayer stack.
Subsequent steps included circuit etching, precise alignment during lamination under high pressure, and application of green soldermask paired with white silkscreen. We applied lead-free HASL surface finish using molten solder coating and hot air leveling to achieve good solderability on every board. Final electrical testing verified continuity and isolation across the full set, with all boards passing without issue. The order was completed in 2.3 days, delivering consistent quality suitable for the customer's requirements.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
