These five single 2-layer FR4 PCBs were produced to 100 × 60 mm dimensions and 1.6 mm thickness with 1 oz copper weight. The 6/6 mil track spacing and 0.3 mm minimum hole size fell within standard geometry, while the custom stackup required careful material preparation to maintain flatness and registration throughout the run. We completed the full sequence from engineering review through electrical testing in 1.6 days, keeping every process parameter matched to the specified HASL Lead Free finish.
Circuit imaging and etching delivered clean copper definition on the green soldermask boards before white silkscreen application. Molten solder coating and hot air leveling created an even, lead-free surface that supports straightforward assembly. Because the order involved only five boards rather than a production panel, we optimized each handling step individually to avoid any edge damage or surface contamination.
Final electrical testing confirmed 100 % net continuity with no repairs required. The combination of standard FR4 construction, conventional feature sizes, and prompt execution resulted in consistent boards delivered exactly to the requested specifications.
