Five units of 2-layer FR4 PCB were built to the given specifications: 84.33 × 127.76 mm outline, 1.6 mm thickness, 1 oz copper, and 10/10 mil minimum track and spacing. The 0.5 mm minimum hole size and default stackup allowed standard processing from material preparation through circuit imaging and etching. With no impedance control required, the job moved through these stages at a steady pace while preserving trace definition and registration.
Matte green soldermask and white silkscreen were applied to deliver clear contrast and surface protection. HASL Lead Free surface finish was formed by molten solder coating and hot air leveling, producing an even, oxidation-resistant layer suited to standard assembly processes. Every board then completed electrical testing to confirm net continuity and isolation.
The full sequence, from engineering review to final inspection, finished in 2.2 days. For this small-quantity order the same process controls used on production volumes were applied, resulting in consistent board quality that meets all dimensional and electrical requirements.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
