Manufacturing Summary
We manufactured five individual 2-layer FR4 circuit boards for this order, each measuring 15 x 41.7 mm and built to a 1.6 mm thickness with 1 oz copper. These compact single PCBs incorporated standard 6 mil trace width and spacing as well as 0.3 mm minimum hole sizes, specifications that align with conventional manufacturing parameters. Following a detailed engineering review, our team prepared the base materials and executed the imaging and etching steps to accurately define the circuitry.
The boards received a white solder mask paired with black silkscreen printing, creating high-visibility markings for assembly. We applied HASL Lead Free surface finish using molten solder coating and subsequent hot air leveling, which ensures excellent solderability without lead content. Full electrical testing confirmed the integrity of every board prior to completion.
Completed in 2.3 days, this low-volume production emphasized precise process control for the specified stackup and finish. The straightforward design allowed efficient execution while maintaining full consistency across the delivered units.
