Production for this order consisted of 10 individual 2-layer FR4 PCBs, each measuring approximately 150 by 85 mm. Built to a standard 1.6 mm thickness with 1 oz copper foil, the boards incorporated 6 mil minimum traces and spacing as well as 0.3 mm holes. Without impedance control requirements, the build followed established processes for conventional FR4 designs and HASL Lead Free finishing.
Engineering review and material preparation confirmed all parameters before circuit imaging and etching defined the conductive pattern. Green solder mask and white silkscreen were applied in sequence, followed by molten solder coating and hot air leveling to produce a uniform lead-free surface. Every board then received full electrical testing to verify continuity and isolation.
The entire run was completed in 5.1 days, yielding ten consistent boards that matched all dimensional, plating, and finish requirements for this single-PCB configuration.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
