This production record covers a batch of five 2-layer FR4 PCBs, each measuring 70 x 115.5mm with 1.6mm thickness and 1oz copper foil. The design featured a standard 10/10mil track and spacing along with 0.3mm minimum hole size, allowing conventional processing methods throughout the fabrication sequence. After completing the engineering review, we prepared core materials and proceeded with precise circuit imaging and etching to establish the conductive patterns.
Green solder mask and white silkscreen were applied in subsequent stages, followed by HASL Lead Free finishing. The process involved molten solder coating and hot air leveling to achieve a uniform, lead-free surface that ensures excellent solderability for through-hole and SMT components. Full electrical testing validated the integrity of every board before final inspection.
Completed within 1.8 days, this small-volume order exhibited reliable consistency in line with its straightforward specifications. The execution highlighted efficient handling of standard 2-layer FR4 PCB requirements without complications from impedance control or finer geometries.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
