This production run consisted of standard 4-layer FR4 PCBs at 1.6 mm thickness with 1 oz copper weight across all layers. Minimum trace width and spacing held at 6/6 mil, fitting conventional geometry that supported stable imaging and etching without requiring advanced fine-line tooling. HASL Lead Free surface finish was applied through molten solder coating and hot air leveling, delivering uniform coverage and reliable solderability for standard assembly processes.
The sequence began with engineering review and material preparation, followed by inner layer imaging, precise layer stack alignment, and high pressure lamination to secure interlayer registration. Solder mask application achieved even thickness and clean pad definition prior to final surface finish. All boards then underwent full electrical testing to verify netlist compliance and isolation integrity.
The order completed in 3.4 days with consistent dimensional stability and layer-to-layer alignment throughout. These execution details confirm repeatable quality for this type of multilayer PCB, providing customers with boards that integrate directly into their target electronics without additional tuning.
Six layer FR4 boards provide optimized routing density and power distribution. They require precise lamination and plating process control to maintain yield and reliability.
