This production record covers manufacturing of ten 2-layer FR4 PCBs, each 100 x 100 mm in dimension with 1.6 mm thickness and 1 oz copper. Featuring standard 6/6 mil track spacing and 0.3 mm minimum holes, these single boards did not require impedance control. We started with engineering review and material preparation, then moved efficiently through circuit imaging and etching stages to define the circuitry.
Green soldermask paired with white silkscreen was applied prior to the HASL Lead Free surface finish. This involved molten solder coating and hot air leveling to produce a flat, solderable surface on the pads and traces. Default stackup parameters were followed, and the entire batch received thorough electrical testing to validate all connections.
The process wrapped up in 1.6 days, yielding a reliable set of PCBs that fully aligned with the provided specifications. Consistency in solder mask application and surface finish quality ensured the boards are ready for assembly and long-term use.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
