The manufacturing of these 15 single PCBs focused on a standard 2-layer FR4 configuration measuring 121 x 121 mm, with 1.6 mm thickness and 1 oz copper weight. Specified with 6/6 mil track and spacing along with 0.3 mm minimum hole size and no impedance control, this order aligned with conventional parameters that allowed efficient processing through our standard fabrication line.
We conducted a thorough engineering review followed by material preparation. Circuit imaging and etching produced accurate conductor patterns on the double-sided boards. Green solder mask and white silkscreen were applied according to specifications, after which molten solder coating and hot air leveling created a uniform HASL Lead Free surface.
All 15 boards then underwent electrical testing, passing with consistent results that confirmed their reliability and readiness for assembly. The complete production was accomplished in 2.1 days, highlighting the dependable outcomes achieved with these straightforward specifications.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
