2 Layer FR4 PCB Production Record #FR4-20260831-085

This order comprised five single 2-layer FR4 PCBs sized 95 × 50 mm with standard 1.6 mm thickness and 1 oz copper weight. The design called for conventional 10/10 mil track and spacing together with 0.25 mm minimum holes, green solder mask, white silkscreen, and HASL Lead Free surface finish. These parameters required no special geometry or impedance control, allowing the factory to follow its established double-sided process flow with predictable material usage and straightforward registration.

Production started with engineering review and FR4 material preparation, followed by circuit imaging and etching to define the copper layers. Solder mask was applied and cured before molten solder coating and hot air leveling created a uniform lead-free finish suitable for through-hole and SMT assembly. Every board then completed electrical testing to confirm net continuity and isolation.

The entire run was delivered in 2.2 days, yielding five consistent boards with even coating thickness and clean hole walls. This small-quantity, standard-specification job demonstrated stable process control and reliable repeatability for everyday FR4 applications.

This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
