Production of this order comprised 50 units of 2-layer FR4 PCBs in a square 121 x 121 mm format. With a standard board thickness of 1.6 mm, 1 oz copper, 6/6 mil trace spacing, and 0.3 mm minimum holes, the design represented conventional parameters well-suited for reliable general electronics. Application of green solder mask, white silkscreen, and HASL Lead Free surface finish completed the build without impedance or via complications.
The factory sequence started with engineering review and material preparation, followed by precise circuit imaging and etching to achieve uniform conductor patterns. Solder mask application preceded the molten solder coating and hot air leveling steps, delivering an even, lead-free finish optimized for through-hole and SMT assembly. Full electrical testing validated each of the 50 boards prior to shipment.
Executed over a period of 2.3 days, the run yielded consistent outcomes with all boards adhering to the specified dimensions and performance criteria. This approach ensured dependable quality for the customer's requirements.
2 layer FR4 PCBs deliver cost-effective solutions for most electronic designs. Their simple structure enables consistent quality and efficient production cycles.
