2 Layer FR4 PCB Production Record #FR4-20260924-035

The manufacturing of these five 2-layer FR4 boards began with a thorough engineering review of the custom stackup and specifications, including the compact dimensions of 42.67 x 26.55 mm and standard 1.6 mm thickness. With 1 oz copper layers and a conventional 10/10 mil track-to-spacing ratio, the circuit imaging and etching processes were carried out using established parameters to achieve clean traces and accurate feature definition on the single boards.

We applied green solder mask and white silkscreen before proceeding to the lead-free HASL surface finish. This involved molten solder coating followed by hot air leveling to create a uniform protective layer on the exposed copper, ensuring excellent solderability for the 0.5 mm minimum hole size. Each board then underwent comprehensive electrical testing to verify netlist compliance.

Completed in 2.2 days, this small production run demonstrated reliable execution from material preparation through final inspection. The straightforward design without impedance control or blind vias allowed us to focus on delivering boards with consistent surface quality and dimensional stability suited for general electronic applications.
